|tundra (tŭn'drə) Pronunciation Key
A cold, treeless, usually lowland area of far northern regions. The lower strata of soil of tundras are permanently frozen, but in summer the top layer of soil thaws and can support low-growing mosses, lichens, grasses, and small shrubs.
Note: There are no trees on the tundra: the vegetation is primarily lichens and mosses.
Note: Tundra is widespread in Lapland and in the far northern portions of Alaska, Canada, and the Soviet Union.
