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.
