Differences between tundras and forests(Adrian Louis)

  
          Did you know that tundras are the coldest biomes in the world?
          Tundra comes from the Finnish word 'tunturi' meaning treeless
          plain. It was noted that it had frost-molded landscapes, extremely
          low temperatures, little precipitation, poor nutrients and short
          growing seasons.          


          Did you know that the first forests weredominated by horsetails,
          clubmosses, and ferns that stood 40 feet tall? It was noted that
          it had much more plants as the tundras have poor nutrients in
          poor soil so the plants cannot survive itincluding the harsh weather
                 

          There can still be some similarities between the tundras and the forests.
          Here are some of the similarities:
  • Both are wet places.
  • Both recieve rainfall.

Huiyi(differences between Tundra and forest)

Forest:

Tropical rainforests are very wet places, receiving heavy rainfall either seasonally or throughout the year. They are close to the equator and get lots of sunlight and warmth. They are havens for millions of plants and animals.

Tropical rainforests have more kinds of trees than any other forests in the world.

Huge numbers of animals live in rainforests, including microscopic animals, invertebrates, fish, reptiles, amphibians, birds and mammals.

Tundra:

The Tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons.The meaning of the word Tundra is treesless plain.The Tundra is covered in marshes, lakes, bogs and streams during the warm months.

Only 1,700 species of vascular plants can be found there.

Only 48 land mammals can be found, although thousands of insects and birds migrate there each year. There are also a few fish species such as the flatfish. There are few species with large populations. Notable animals in the Arctic tundra include caribou, musk ox, arctic hare, arctic fox, snowy owl, lemmings, and polar bears.

ken's differences between the tundra and the tropical forests

The main  differences between the two climates is not enough rain in tropical wet and dry climates to support rain forests. Tundra climates are dry, with a brief, chilly summer and a bitterly cold winter.Tundra is located on earth's poles, which receive little sunlight making it extremely cold. Little vegetation can become established because of the permafrost that prevents root systems, as well as the winds that clear miles of open land.

Differences between the tundra and the tropical forest(wan xuan)

The tundra is located on Earth poles which receive little sunlight ,making it extremly cold.In contrast,tropical rainforest receive direct and constant sunlight which evaporate large amounts of water into the atmosphere only to drop back down again.

 Differences between rainforest and tundra

CLIMATE
Rainforest
  • Warm and wet climate
  • In most tropical rainforests, it rains everyday.
  • Tropical rainforests grow in a narrow zone near the equator
  • In an average year in a tropical rain forest, the climate is very humid because of all the rainfall, which amounts to about 250 cm per year.
  •  The rain forest has lots of rain because it is very hot and wet.
  • A lot of the rain that falls on the rain forest never reaches the ground. It stays on the trees because the leaves act as a shield, and some rain never gets past the trees to the smaller plants and grounds below.
Tundra
  • Low temperature
  • The climate in a tundra biome consists of freezing cold and dryness in the winter and cold summers.
  • The tundra ground is a barren place, often covered with rocks.
  • Most water on the tundra is frozen within the soil. (The permanent frozen soil is called permafrost.)
  • Summers last for a very short time.
  • Winters are very cold.

PLANTS
Rainforest
  • Tropical rainforests are home to a huge number of different flora and fauna.
  • The main plants in this biome are trees.
  • Trees in this climate reach a height of more than 164 feet. They form a canopy. The forest floor is called understory. The canopy also keeps sunlight from reaching the plants in the understory.
  • The plants that make up the understory of a rainforest have adapted to the small amount of sunlight that they receive.
  • Ferns and mosses do well, along with epiphytes. These are plants that grow on other plants. They can be found growing on branches of tall trees where they can get sunlight.
Tundra
  • Trees do not grow there.

  • Plants in the tundra are low-growing
  • Plants group together to withstand the strong winds and cold temperatures
  • They have adapted so that photosynthesis (getting food from sunlight) can occur in the low light and cold temperatures.




ANIMALS

Rainforest

  • Rainforests has a rich diversity of animal species.
  • Insects make up the largest single group of animals that live in tropical forests.
  • Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2% of Earth's surface, rainforests house more than 50% of plants and animals on Earth.
Tundra
  • Animals that lives in the tundra have special adaptations that allow them to survive the
    extreme temperatures and conditions that are present in a tundra
  • Some animals have grown thick fur which turns white in the winter. Others find a place to hibernate during the winter months.





Jei Min ( tundra and the forest)

Condition- They're almost completely opposite. Tundra is located on earth's poles, which receive little sunlight making it extremely cold. Little vegetation can become established because of the permafrost that prevents root systems, as well as the winds that clear miles of open land. In contrast, tropical rainforests receive direct and constant sunlight, which evaporates large amounts of water into the atmosphere only to drop back down again. Though rainforests only occupy 3% of the earth, it contains over half of the worlds species - the most diverse biome in the world.



Animals in the tundra- Animals that live in the tundra have special adaptations that allow them to survive the
Polar Bear




extreme temperatures and conditions that are present in a tundra. A good example

of an animal with special adaptations is the Arctic Fox. The Arctic Fox has short ears

and a short, round body with a thick coat to minimize the amount of skin exposed to

the frigid air. There is a low amount of biodiversity in the tundra so fluctuations in

one animal population will effect populations in another. An example of this would be

that if in a certain year there is a lower amount of Lemmings than usual, then the

population of Snowy Owls, who feed mostly on Lemmings, will also decrease.

Animals that live in the tundra-
Caribou
Arctic Fox
Arctic hare
Snowy Owl
Musk Ox
Rock Ptarmigan



Animals in the rainforest-On the forest floor, the lowest layer, live thousands of species of ant, termite, beetle and bug. Butterflies are important rainforest insects. Butterflies feed on nectar, and are important because they pollinate flowers.


Many species of birds live in the canopy layer of the rainforest. The gray parrot is one species of bird that lives in the African rainforest. They can fly very fast and are noisy birds. They can be taught to talk, so they make popular pets. Hornbills are another species of bird in the African rainforest. They eat fruits and insects. The bird in the picture on the left is a hornbill. Both parrots and hornbills make their nests in holes in the trees.

Frogs and toads occupy the rainforest because they like the moist environment. Tree frogs have flat bodies and round toes that help them cling to leaves and branches. Snakes live in the trees and alligators and crocodiles live in rainforest rivers.










    
















(Jun Wuen) tundra and forest

  The Arctic tundra is a vast area of stark landscape and is frozen for much of the year. The soil there is frozen from 25–90 cm down, and it is impossible for trees to grow. Instead, bare and sometimes rocky land can only support low growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen. There are two main seasons, winter and summer, in the polar tundra areas. During the winter it is very cold and dark, with the average temperature around −28 °C (−18.4 °F), sometimes dipping as low as −50 °C (−58.0 °F).
  The tundra is a very windy area, with winds often blowing upwards of 48–97 km/h However, in terms of precipitation, it is desert-like, with only about 15–25 cm falling per year. During the summer, the permafrost thaws just enough to let plants grow and reproduce, but because the ground below this is frozen, the water cannot sink any lower, and so the water forms the lakes and marshes found during the summer months.
  A forest is an area with a high density of trees. There are many definitions of a forest, based on the various criteria.[1] These plant communities cover approximately 9.4% of the Earth's surface (or 30% of total land area), though they once covered much more in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere.
  Forests sometimes contain many tree species within a small area (as in tropical rain and temperate deciduous forests), or relatively few species over large areas. Forests are often home to many animal and plant species, and biomass per unit area is high compared to other vegetation communities.

difference between tundra and forest (brandon)

  A forest is an area with a high density of trees.Forests can be found in all regions capable of sustaining tree growth, except where natural fire frequency or other disturbance is too high, or where the environment has been altered by human activity.Forests can be classified in different ways and to different degrees of specificity. One such way is in terms of the "biome" in which they exist, combined with leaf longevity of the dominant specieshe latitudes 10° north and south of the Equator are mostly covered in tropical rain forest. As a general rule, forests dominated by angiosperms (broadleaved forests) are more species-rich than those dominated by gymnosperms (conifer, montane, or needleleaf forests), although exceptions exist.

 
 
Arctic tundra occurs in the far Northern Hemisphere.The tundra is a very windy area, with winds often blowing upwards of 48–97 km/h (30–60 miles an hour). However, in terms of precipitation, it is desert-like, with only about 15–25 cm (6–10 inches) falling per year (the summer is typically the season of maximum precipitation). During the summer, the permafrost thaws just enough to let plants grow and reproduce, but because the ground below this is frozen, the water cannot sink any lower, and so the water forms the lakes and marshes found during the summer months. Although precipitation is light, evaporation is also relatively minimal.




Jie Xi (Differences between Forests and Tundra)

Differences between Forests and Tundra
Forests are the warmest in all biomes while Tundra is the coldest in all biomes. Forests have many different tree species while Tundra has a few or no trees at all. Forests are home to many animal and plant species,and biomass per unit area is high compared to other vegetation communities,while Tundra has frost-molded landscapes,extremely low temperatures,little precipitation,poor nutrients,and short growing seasons.

(Javier Tham) tropical forest and tundra

Tundras are the coldest places in the world. It can even be at 0 degree Celsius at its warm seasons. Only some of the animals can live there. There are not much nutrients in the soil but there are still some like the cushion plant. Most animals grow in the tropical forest than any other forests. People should protect this biomes in order to prevent some of the animals there from extinction .

Difference between the tundra and the forests (Bin Sheng)

Climates
The climate in the tundra is very cold while the climate in the forest is extremely hot and wet.The tropical forest recieve alot of rainfall while the tundra does not recieve much rainfall most of the time.

Plants

The tropical forest have about the world's half species living there. As for the tundra it is mostly a barren place. Plants that live there often are small and close to the ground. They also live in groups but the outer one always die protecting the inner plants. Exmaple of the tundra plant is the cushion plants.

Animals
There are little life in the tundra. In order for animals to survive there they must adapt to the climate. Examples of a animal that live there is the polar bear. Animals that live in the tropical forest are mostly extinct or endangered.

Even though the tundra and the forests is different people should protect them.

You could say that they're almost the complete opposite. Tundra is located on earth's poles, which receive little sunlight making it extremely cold. Little vegetation can become established because of the permafrost that prevents root systems, as well as the winds that clear miles of open land. In contrast, tropical rainforests receive direct and constant sunlight, which evaporates large amounts of water into the atmosphere only to drop back down again. Though rainforests only occupy 3% of the earth surface, it contains over half of the world’s species – which makes it the most diverse biome in the world!

differences between tropical forest and tundra ( Jia Hui )

                                                                   What is the Climate like?                                                 

        The tundra is cold while the tropical forest is hot and damp.Tropical forests are very damp places,receiving heavy rainfall either seasonally or throughout the year.They are close to the equator and get lots of sunlight and warmth.Temperatures are uniformly high (about 20 to 35 degree).They usaully receive more than 200 cm rainfall per year.Tundra is famous for its frost-molded landscapes ,extremely cold temperature and short growing seasons.Tundra is either located in the northern hemisphere or on mountains where trees cannot grow.
                                                                      What kind of animals live there?
           In the tropical forests,many animals live there.Here are some examples: alligator,amphibians,anaconda,ants,apes,assassing bugs,bats,binturong,birds,emerald tree boa and butterflies.The animals that live in tropical forests does not have thick fur while the animals living in the tundra have thick fur which help the animals to keep warm in the harsh enviroment.Here are some examples of animals living in the tundra:pikas, marmots, mountain goats, sheep, elk ,grouselike birds ,springtails, beetles, grasshoppers and butterflies.
                                                                  Protected                                                                               
          Even though they are different,they still needed people to protect and respect them.Today, people are trying to lessen logging in forests and carrying out less activy in the tundra.We should not destroyed them as they are the most beautiful work of Mother Nature.

Differences in tundra and tropical rainforests (Wong Wai Teng)

          The tundra and the tropical rainforests have its own climate and temperature. They also have different kinds of animals and plants living on it. 

 Climates
          The tundra climate is found along arctic coastal areas. Polar and arctic air masses dominate the tundra climate and the winter season is long and severe. A short, mild season exists, but not a true summer season. The temperature ranges from -22 degrees to 6 degrees.                                                               

 The climates in tropical forests are different. The summers are warm and very humid. It rains a lot in the winter. The average temperature is about 18 degrees.


Plants and animals
          Surprisingly, there are as many as 1,700 different plant species that grow in the tundra. The tundra plants consist mostly of mosses, grasses, lichens, sedges, and shrubs. About 400 types of flowers bloom in the growing season, which lasts just for 50-60 days. There are only about 48 species of land mammals occurring in the tundra biome. The tundra animals mainly are slightly modified forms of foxes, wolves, rodents, hares, and shrews.

 

The tropical forest flourishes in places that are both warm and rainy throughout the year. This kind of weather is perfect for plants, allowing them to keep their leaves and grow continuously, instead of dying and shedding their leaves in winter. Tropical rainforests are home to more plant species than any other biome – and they contain so many animal species that no one has even tried to count them.


Conclusion, tundra and tropical rainforests are different mainly due to the climate and temperatures.

The End!

Grace: Difference between forest and tundra

The climate of a tundra:
        It is cold through all months of the year Summer is a brief period of milder climates when the sun shines almost 24 hours a day. It has been called "the land of the midnight sun". But even the sun can't warm the tundra much. The short summer lasts only 6 to 10 weeks. It never gets any warmer than 45 or 50° F. The warmer weather causes a layer of permafrost, ice that never goes away in the ground, to melt, creating bogs and shallow lakes that don't drain. They breed stinging insects, which make life even in the summer miserable for the inhabitants of the tundra. The wind blows constantly, whipping around the small plants. During the long winter months the sun barely rises and it is dark for most of the day. Bitter cold winds scud across the barren snowscape, exposing high plateaus to barren ground. Winter temperatures don't reach above 20° F and average -20° to -30°F. Endless hours darkness settle in and the winds blow even harder. The snow that falls is blown off the high plateaus and collects in the valleys. Animals hunker down, able to find only enough food to keep warm. The tundra is an unusually cold and dry climate. Precipitation totals 6-10 inches of rain a year, which includes melted snow. This is almost as little as the world's driest deserts. Coupled with strong and drying winds, the tundra is an extreme weather biome. The tundra seems like a wet and soggy place because the precipitation that falls evaporates slowly, and because of the poor drainage caused by the permafrost. You can find the tundra climate in Köppen's E climate category. The Estands for ice climates. The average temperature of the warmest month is below 50° F. The tundra climate spans from most of Greenland to parts of Alaska, northern Canada, and northern Russia. The latitudinal range is 75° N to 60° N. Tundra climates can be found on the coastal areas of the arctic. The ocean water keeps the climate from falling to the extreme temperatures found in the interior of the continents.

The climate of a forest:
       Tropical forests are very wet places, receiving heavy rainfall either seasonally or throughout the year. They are close to the equator and get lots of sunlight and warmth. Temperatures are uniformly high - between 20 and 35°C. They usually receive more than 200 cm rainfall per year.


The living things in tundra:
       There are 1,700 species of vascular plants and only 48 land mammals can be found, although thousands of insects and birds migrate there each year for the marshes. There are also a few fish species such as the flatfish. There are few species with large populations. Notable animals in the Arctic tundra include caribou (reindeer), musk ox, arctic hare, arctic fox, snowy owl, lemmings, and polar bears (only the extreme north).       


The living things in forest:
       Flowers like orchids and bromeliads (members of the pineapple family) grow directly on trunks and larger branches - they are called epiphytes. Birds and butterflies insects easily reach these flowers and act as pollinators. Where rain falls all year round, the forests are evergreen - the trees do not lose their leaves, or do so at different times.

Sze Ying (Difference between tundra and tropical forest)


    The tundra is located at the top of the world, near the North Pole. It is extremely cold. Sometimes, the temperature can go as low as -70°C. Some of the plants that live in the tundra are cotton grass, cushion plants and many others. The animals that live in the tundra must adapt the weather there to survive. Some of the mammals are the arctic fox, polar bear, musk ox and many more. Some of the birds are snowy owl, tundra swan, snow bunting and many more.

    The average temperature in the tropical forest is 20-25° C. Some of the plants that live in tropical forest are orchids, ferns, mosses and many more. The animals that live in the tropical forest include birds, bats, small mammals and insects.

Tundra is located on the earth's poles,which receives a little sunlight, making it very,very,very,very,very cold.Little vegetation grows there because of the permafrost.

Tropical rainforests receive a lot of sunlight,therefore a lot of evaporation and it will then become rain;thats why tropical rainforests receive the most amount of rainfall.The thing that surprises me is that rainforests cover only 3% of the earth, but still contains half of the world's animal species.

differences between alpine and artic tundras by Ken

  The differences between alpine and arctic tundra are their locations and drainage.While the arctic tundra experiences very limited drainage, the alpine tundra is well drained.The other difference between alpine and arctic is that the arctic is covered with snow and little animals and alpine is not covered with snow and has hundreds of species of animals.

Differences
  • Alpine Tundras occur in climatically stressed enviroments at high mountainous altitudes. Alphine Tundra can also occur in mountaintops at tropical latitudes, although this vegetation type is much more common in temperature regions.
  • Arctic Tundras occur in southern areas. On wet sites, the Arctic Tundra of North America develops as relatively productive wet meadows dominated by a tussock-forming cottongrass(Eriophorum vaginatum), while better-drained sites are dominated by shrubs such as willow.

Differences(Melissa)

            The arctic is the region of the world that has at least one 24 hour period each year that the sun does not rise and at least 24 hour period each year that the sun does not set.This is known as the arctic circle.As such,the arctic tundra is located within the arctic region.alpine is that area of the planet which is above the tree line.The tree line determines by how cold a region gets.I believe that for trees to grow,the temperature must not go below a certain temperature.Hence you will notice the tree line(or Alpine)levels differs depending upon the variant temperatures in a particular region.In short the colder the area gets,the lower the tree line.In the final analysis,the difference between the two types of tundra is the location.Basically the alpine tundra is in the mountains and the arctic tundra is like the snowy icy place that we think about mostly.

Sze Ying (Differences)

    The Arctic Tundra is located in the far Northern Hemisphere, north of the taiga belt which cannot grow trees.It has two seasons: winter and summer. In winter the temperature can go as extreme as -70°C. It's average temperature can be around −28 °C. There are about 1700 types of plants living in the Arctic Tundra. There are 48 land animals that make Arctic Tundra their home, but sadly there are no reptiles and amphibians. Some of the animals include reindeer, musk-ox and many others. 

    Alpine Tundra are normally at an altidude of about 10,000 feet or more. They cannot contain trees as it has high altidude. Very few animals live at Alpine Tundra.Some of the animals that live in Alpine Tundra are yellow bellied marmots, pikas and ptarmagins. They have unique adaptions to live in the Alpine Tundra. There are only about 200 types of plants living in the Alpine Tundra.One of them is the cushion plants.They look like flattened cushions hugging the ground.   

Nur Syafiqah (Differences of Artic Tundra and Alpine Tundra)


          Do most of you know that there are two types of tundra? There are Artic Tundra and Alpine Tundra. Artic Tundra are found at the Southern Hemisphere while Alpine Tundra are fount at the Indian Peaks region of Colorado. The climate of the Alpine tundra is exceedingly harsh. There, snow remains as permanent snow fields. What about the climate of Artic Tundra? Artic Tundra in the other hand have two seasons which are the winter and the summer. During summer, the sun is present almost 24 hours a day. This Sun however, warms the tundra upto a range of about 30c to 12oc. During winter however, there are several weeks where the sun never rises. The temperature is around -28 to -70 degree.


          How about plants? Do you know that there are plants that live in both the tundra. For Arctic Tundra, there are around 1700 species of plants whereas for Alpine Tundar there are only 200 different species of plants. Some of them which grows in the Artic Tundra are like the Arctic Moss, Arctic Willows, Bearberry and many more. On the other hand, plants which grow in the Alpine Tundra are the Alpine Bluegrass and many more

          If there is plants there is sure an animal which live there. Yes, some animals can live on Tundra. It is very shocking but that is the truth. Loons, terns, pengins, polar bear, musk ox, grey wolf and many more are examples of animals that live in the Artic Tundra. Beetles, pika, marmots, white-tail parmigan, grouse and many more are examples of animals which lives in the Alpine Tundra.

Here are some pictures of Artic Tundra...

Jie Xi(differences between the Arctic and Alpine tundra)

The differences between the Arctic and Alpine Tundra



The differences between the two are :


Alpine biomes are found in the mountain regions all around the world while Arctic biomes are found almost entirely in the Northern Hemisphere. In Alpine Tundra,the summer average temperature ranges from 10 to15 celcius while in Arctic Tundra,it ranges from 3 to 12 celcius. In Alpine Tundra,in the winter,temperature are below freezing while in Arctic Tundra,the average temperature in winter are -28 celcius to -70 celcius. In Alpine Tundra, there are only about 200 species of Alpine plants while in Arctic Tundra,there are about 1700 species of Arctic plants. Arctic Tundra is always cold while Alpine Tundra is warmer.  
Alpine tundra

Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. The growing season is approximately 180 days. The nighttime temperature is usually below freezing. Unlike the arctic tundra, the soil in the alpine is well drained. The plants are very similar to those of the arctic ones and include:
  • Tussock grasses, dwarf trees, small-leafed shrubs, and heaths

  • Animals living in the alpine tundra are also well adapted:

 
       •Mammals: pikas, marmots, mountain goats, sheep, elk




       •Birds: grouselike birds



       •Insects: springtails, beetles, grasshoppers, butterflies






   


























    

(Micheal Jackson)ALASTAIRANG

(Micheal Jackson Biography)
Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American singer, dancer and entertainer. Referred to as the King of Pop, he is recognized as the most successful entertainer of all time, and one of the most influential. His contributions to music, dance and fashion,[1] and a much publicized personal life, made him a global figure in popular culture for over four decades.







Alongside his brothers, he made his debut as lead singer and youngest member of The Jackson 5 in 1964. He began his solo career in 1971. His 1982 album Thriller remains the best-selling album ever, with Off the Wall (1979), Bad (1987), Dangerous (1991) and HIStory (1995) among the world's best-selling albums ever. He is credited with having elevated the music video from mere promotional tool into an art form: his videos for Billie Jean, Beat It and Thriller made him the first African American artist to amass a strong crossover following on MTV. Jackson popularized a number of physically complicated dance techniques, such as the robot and the moonwalk. His distinctive musical, vocal style and choreography are credited with having transcended generational, racial and cultural barriers.






Jackson is one of the few artists inducted into the Rock and Roll Hall of Fame twice. Other achievements include several Guinness World Records (including Most Successful Entertainer of All Time), Grammy Awards (including the Living Legend Award and a Lifetime Achievement Award) and 26 American Music Awards, more than any other artist, 24 in a solo capacity and including one as Artist of the Century. He had 17 number one singles in the US, including four as a member of the Jackson 5, and estimated world sales of 750 million records,[2] making him the highest-selling recording artist ever.[3]






Jackson's personal life generated controversy for years. His changing appearance was noticed from the late 1970s onwards, with changes to his nose, and skin color, causing much media speculation. Though no charges were brought at the time, he was accused of child sexual abuse in 1993. In 2005 he was tried and acquitted of similar charges. He married twice, first in 1994 and again in 1996. He brought up three children, one born to a surrogate mother. While preparing for the This Is It concert tour that would have started in mid-2009, Jackson died at the age of 50 after suffering from cardiac arrest. He reportedly had been administered drugs such as propofol and lorazepam, and his death was ruled a homicide by the Los Angeles County coroner. His death triggered an outpouring of grief from around the world, and his globally live-broadcast memorial service attracted an audience of millions of people.[4] His death also precipitated a huge surge in his album sales, resulting in his becoming the best-selling artist of 2009 in both the United States and globally, with sales in excess of 8.2 million units in the U.S.[5] Also in the United States, he became the first artist ever to have four of the top 20 best-selling albums in a single year.[6] Globally, he posthumously sold 29 million albums, and had an unprecedented eight of the top 25 best-selling albums worldwide.[7]

Xin Hui (differences between arctic tundra and alpine tundra

Arctic tundra

• found in the Northern Hemisphere

•animals such as caribou, polar bear, musk ox, wolf and wolverine live there

•plants like arctic moss, arctic willow and bearberry grow there

•has a dry and cold climate the air temperature can be as low as -60˚C

 
Alpine tundra

•found in mountain regions

•animals such as pika and ptarmigans live there

•plants like shrubs, grasses and grass-like plants and forbs grow there


•summer temperature range between -12˚C to 10˚C
  Arctic tundra comprises about 25 million square kilometres but Alpine comprises 9.5 square kilometres.
  Alpine tundra soils are drier but Arctic tundra ar not dry during the growing season.
  The diffrence between alpine and arctic is that the arctic is covered with snow and little animals and alpine is not covered with snow and has hundreds of species of animals .

Valerie(Differences between Artic tundra and Alphine tundra)

Differences:

Alpine biomes are found in the mountain regions all around the world while Arctic biomes are found almost entirely in the Northern Hemisphere.

Usually, Alphine summer temperatures range from 10 to 15°C . The Artic tundra's sun, however, only warms the tundra up to a range of about 3°C to 12°C. 

Because of the severe climate of the Alpine biome, plants and animals have developed adaptations to those conditions. There are only about 200 species of Alpine plants. The arctic tundra biome has a relatively low biodiversity. There are around 1700 species of plants that live in this zone. Even though this zone has very few species, the number of individuals in each species that make this biome a home for part of the year is very large.

-The End-

Huiyi(The Tundra)

TThe Tundra
Artic Tundra:
The Artic Tundra has two seasons, winter and summer.When the sun is up, it is up twenty-four hours a day.The sun only warms up the tundra from three degrees to twelve degrees. Some weeks, the sun never comes up. The tempreture drops drastically. The average tempreture is minus twenty-eight degrees but it can drop to about minus seventy degrees.

There are around 1700 species of plants that live there. There are almost no reptiles or amphibians. There are only 48 land mammals that make this habitat their home.Even though fewer animals make this habitat their home, the animals that live there, live in large numbers.

Many animals migrate to the tundra in the summer months to take advantage of the lack of predatorsand abundant amounts of food. Snowy Owls breed on the ground in the summer months, and prey on small rodents. Musk oxen, a smaller cousin of the Ox feeds on the grasses in small herds.

.Alphine Tundra:
In the summer, average temperatures range from ten to fifteen degrees . In the winter the temperatures are below freezing. The winter season is very long and can last from October to May. The summer season is short and may last from June to September. The temperatures in the Alpine biome can also change from warm to freezing in one day.

Because the cold climate of the Alpine biome, plants and animals have adapted to those conditions. There are only about 200 species of Alpine plants. Because of the cold and wind, most plants are small and groundcover plants which grow and reproduce slowly. They protect themselves from the cold and wind by hugging the ground. Taller plants or trees would soon get blown over and freeze. Most Alpine plants can grow in sandy and rocky soil. Plants have also adapted to the dry conditions of the Alpine biome.

There are only warm blooded animals in the Alpine biome, although there are insects. Alpine animals adapt to the cold by hibernating, migrating to lower, warmer areas, or insulating their bodies with layers of fat. Animals will also tend to have shorter legs, tails, and ears, in order to reduce heat loss. Alpine animals also have larger lungs, more blood cells because of the increase of pressure and lack of oxygen.


Due to global warming, the glaciers in the Tundra are melting. We must pevent more of these from happening.
