Term
Tundra
Definition
a massive biome that extends in a continuous belt across Canada, Alaska, Asia, and Europe; characterized by very little precipitation (usually < 25 cm annually), permafrost, and small, slow-growing plants such as grasses and mosses; the growing season is limited to a brief period of about eight weeks during the summer, preventing any significant tree growth
