Ferne Corrigan explains how people, animals and plants have adapted to survive the harsh tundra environment.
The tundra is a cold, treeless region that is found in the far northern hemisphere, near the Arctic Ocean. The tundra has unique environmental characteristics.
Derived from the Finnish word tunturia, meaning treeless or barren land, tundra is the coldest and driest of all biomes. Despite these extreme conditions, the tundra is home to several unique species of plant and animal. Learn the difference between arctic and alpine tundra, and what impacts melting permafrost could have on our changing planet.
The Tundra and Ice Biomes of the Arctic and Antarctic. In this video we explore how the weak sun leads to cold temperatures year round and what kind of plants and vegetation, if any, can survive here. Moss and lichen are the most common in the tundra, but upon the ice sheet of Greenland and Antarctica, nothing survives the year-round freeze. We find the tundra along the coasts of Siberia in Russia, in the north of Alaska, and in northern Canada, which possesses most of the treeless tundra in the world by land area, from the Northwest Territories to Nunavut. The coastal areas of Greenland are also in the tundra biome.
Biomes exist on land and in oceans and differ according to their location and geographic characteristics.
Topography (the shape of the land), climate and soils mean similar land biomes can have different species of plants and animals.
Food can be produced from different biomes when people change the environment for example by ploughing the land, building greenhouses to grow plants, draining swamps and wetlands, building terraces on slopes etc.
