occurs in the far Northern Hemisphere, north of the taiga belt. The word “tundra” usually refers only to the areas where the subsoil is permafrost, or permanently frozen soil. Permafrost tundra includes vast areas of northern Russia and Canada. Arctic tundra contains areas of stark landscape and is frozen for much of the year.
