Permafrost
The permanently frozen ground in the northern latitudes is called permafrost. The layer closest to the surface that thaws during the summer is also part of the permafrost, but is called the active layer. Permafrost is a major feature of the tundra biome.In physical geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes from Kildin Sami tūndâr, which means "uplands, treeless mountain tract." There are two types of tundra: Arctic tundra (which also occurs in Antarctica) and alpine tundra. In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline.

Tundra is a cold, treeless region with a short growing season and a layer of permafrost, or permanently frozen subsoil. Arctic tundra occurs in the Arctic region; alpine tundra is found in high mountains scattered all over the world. The temperatures are generally a little higher and the growing season longer in alpine than arctic tundra, and there are some different species of plants and animals. However, both types of tundra still have a layer of permafrost. See Tundra by Peter Moore (Chelsea House, 2006).
