What is a tundra
The tundra is a large, barren region with no trees. In fact, the word tundra comes from the Finnish word tunturia, which means “treeless plain.” Areas of tundra lie between the permanent ice of the far north and the northern forests of North America, Europe, and Asia. They cover about 20 percent of Earth’s surface. They are some of the coldest places on Earth.
Life in tundra
Only low-growing plants, such as mosses and shrubs, can survive in the tundra. Plantlike living things called lichens also grow there.
Tundra animals must be able to survive long, cold winters. Many birds live there in the summer, but few stay through the winter. Some common tundra animals are reindeer, Arctic foxes, snowy owls, musk oxen, and polar bears.
Very few people live in the tundra. Arctic peoples, including the Inuit, tend to live in places where hunting and fishing can provide enough food year-round.
Where are tundras located
undra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia. Much of Alaska and about half of Canada are in the tundra biome. Tundra is also found at the tops of very high mountains elsewhere in the world.
Types of Tundra
Arctic tundra lies in northern Europe, Russia, Alaska, Canada, and Greenland. In those areas the winter temperature may be as low as −25 °F (−32 °C). The summer temperature may rise to only 40 °F (4 °C). Because of these cold temperatures, the Arctic tundra has a permanent layer of frozen soil, called permafrost. Some permafrost reaches as deep as 1,500 feet (457 meters).
Alpine tundra lies farther south than Arctic tundra. Alpine tundra is found in high mountains above the tree line. (The tree line is the highest place where trees can grow.) They have short, cool summers and less extreme winters than Arctic tundra. Alpine tundra does not have a layer of permafrost.
Tundra may be flat, hilly, or mountainous. Little plant life grows on the bare or rocky ground. Tundra in coastal areas tends to be foggy. Snow covers the tundra for more than six months of the year.
Features of a Tundra
Grizzlies are found on the Alaskan and northwestern Canadian tundra. They are considered a subspecies of the brown bear. Most grizzly bears are found in the northwestern part of North America. The grizzly bear's habitat can include forests, mountains, meadows, and valleys
The tundra is so dry and its so cold
The mountain hare lives in the Arctic tundra (icy, dry, and windy land), grasslands, woodlands, and sometimes in lowlands. It has a brown coat that changes to white during the winter months in colder habitats. In warmer habitats, its coat stays brown all year round.
