  2. The Arctic Tundra is the earths newest biome • It formed about 10,000 years ago • Located at 55˚to 70˚North latitude, tundra covers about 20% of the earths surface • Most tundras are located in the northern hemisphere due to strange conditions in the southern hemisphere • This biome has a permafrost for most of the year,the soil is frozen 9-30 inches down Basics

  3. There are two seasons, winter and summer • Winter average temperatures are about 18 degrees farenheit, while the summer is 54. • The shift from one season to another is very rapid • Desert like rainfall levels are usual, 6–10 inches fall per year • Due to a lack of trees and geographic area there are constant winds throughout the tundra Climate

  4. Since there is a permafrost trees cannot root, therefore do not grow • Bare rocky land facilitates moss, heath and lichen Plant Life

  5. 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 Notable animals: -caribou -arctic hare -snowy owl -flat fish Fauna
