Don't like the cold? If not, then it is probably a good idea to stay away from Earth's tundra biomes. Tundras can be found circling the Arctic Ocean throughout North America and Asia.
A tundra is like a very cold desert, getting less then 25 cm (9.8 inches) of rain and snow per year. The moisture that the Tundra does receive ends up locked in a layer of permanent frost called the permafrost. Even in spring, summer and fall, which all together only last about three months, this layer of permafrost never thaws.
In the summer, the surface snow melts, creating pools of water, which are used by many plants and animals. During this short warm season, the tundra comes to life. Many flowers, insects, birds, and other animals can be seen. Very quickly, summer ends, and it is back to the long, harsh, cold winter.
