Tundra

By: Devan George
=1. Geography: = One geographic location considered to be tundra is the Iceland. Though it is very cold, it is still very beautiful!

=2. Altitude above sea level: = In the Alpine tundra, the permanent snow line comes to about 15,000 ft. (4572 m) above sea level. =3. Appoximate Latitude of the Biome: = The average range of latitude in the tundra is 75° N to 60° N. = 4. **Soil Type:** = The soil in the tundra is called permafrost. This is a layer of dirt that freezes in the winter and only thaws to a few centimeters below the surface. This causes the ground to become soggy and wet then refreeze after the short summer ends. This is what leads to the small amount of plant life in this biome. =** 5. Climate: **= The climate in the tundra is mostly rainy and very cold. The summers are short and the highest temperature during that time is 50° F. Then, during the long and harsh winter, the temperature never goes above 20° F and the average during that time is -20° to -30°F. = 6. **Primary Regions:** = The primary regions o the world that are considered to be tundra are all very far north. The land areas surrounding the North Pole, but not including it (the pink areas below).

=7.Plant Life: =

﻿Not many plants are able to grow in the tundra, because of the perminantly frozen layer of dirt, called permafrost.Two examples of plants that live in the tundra are Bearberry and Pasque Flowers. =     = =﻿ = =8.Animal Life: = Not many animals live in this area either, because of the small amount of plant life. Caribou and the arctic Terns. =9.Enviromental Concern: = The main enviromental concern in the artic tundra is soil erotion, which leads to the depleation of plants and therefore, depleation of wildlife in this area. Soil erotion is caused by lack of vegetation, which means there are poor root structures holding the soil in place. Also, causeing loss of plant life is the large amount of caribou and bison herds that move through the tundra, the larger they are in number the more they eat.
