Differences between tundra and tropical forest (Chong En Qing)

Caribou are one of the significant large mammals found on Arctic tundras.


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 rainforest only occupy 3% of the earth, it contains over half of the worlds species - the most diverse biome in the world.
