Transcript of Arctic Tundras

By: Abby, Will and Ian Arctic Tundras Plants Not many plants can survive in the tough climate of the arctic tundra. Only plants like lichens, mosses, sedges, and some flowering plants. Most of these plants grow close to the ground. They do this to avoid the cold wind. The ground is very cold which make trees not able to grow. Animals Climate The climate of the Arctic is snowy and cold. It is still cold in the summer but animals like to come and live there and eat insects. There is also a lot of permafrost under the ground which makes it hard for plants to grow. Very little snow or rain fall falls there. The average temperature of the tundra is around -28°C while extremes can dip to -70°C. Discription Fun Facts In the winter the sun never rises, in the summer it never sets
Only small strong plants are able to survive in the arctic
The frozen ground in arctic tundras are called permafrosts
Animals such as the Arctic fox blend in with the snow by changing colors
Mosses and Leeches grow on surfaces on rocks
Birds migrate to the arctic to enjoy the insects and long summer days
The arctic tundra is also known as the "Cold Desert" GOODBYE Arctic tundras are a type of biome. Tundras normally have a cold climate. The tundra also has many different types of animals. They also have many plants that have to survive the harsh climate. Animals in the arctic tundra have to adapt to the climate. Most of the sea animals (seals and whales) have thick layers of blubber to keep them warm. Blubber is basically fat on the animal. Land animals have a lot of fur on their bodies to keep them warm. Many animals that are on land hibernate so they do not die. Some land animals are, Polar bears, Musk ox, Caribou, Arctic wolves, Hairs and many birds.
