The word Tundra originated from the Kildin Sami word, tūndar meaning “uplands”. Also known as the treeless mountain tract. The tundra is a biome that frequently suffers severe low temperatures. These low temperatures hinder the plant life causing short growing seasons and often times it doesn't allow trees to grow.

The names Antarctic Tundra, Arctic Tundra, and Alpine Tundra are the 3 main types of tundra. The Arctic Tundra is found north of the “snowforest” or taiga belt in the Northern Hemisphere and has only 2 seasons in the polar regions. A winter season and a summer season. Permafrost refers to the frozen soil of the tundra in the winter season.

There are also no trees found in it because of the climate. Unlike the Arctic Tundra the Alpine Tundra does not have permafrost because the soil drains the

It is classified into the group ET which means that it experiences at least one month where the average temperature is above 0 degrees celsius but does not exceed 10 degrees celsius. This means that there will almost always be snow and ice on the ground. This area is generally thought of as hostile to woody vegetation. relies on is its stealth which is improved by having a bright white pelt that blends in with the environment. The wolf also has small ears that help enhance its hearing and ability to stalk prey. All of this helps to improve the wolfs stealth. Some commonly found plants in the Alpine Tundra are the Bearberry, Caribou Moss, and Tufted

As a result this extremely rocky land is capable of growing only plants such as
(calliergon giganteum or arctic moss) lichen, moss, and heath that only need the first few inches of soggy soil to grow. These plants have to be able to endure little sunlight and 100 mph winds. The tundra receives on average just 30 cm rain and the soil lacks the needed nutrients to grow bigger plants. One such plant is the Diamond-leaf

Trees need a lot more room than just a few inches of wet soil to grow and the frozen ground is to hard for their roots to penetrate. This is why the few trees that are able to grow never get as big as they could be. Even through this many animals are able to find
