A tundra is a place with very low temperatures and very little rain. Winters in the tundra are long and extremely cold. Summers are short, mild, and cool.
Some animals living in the tundra are prepared for the cold weather. For instance, foxes, reindeer, caribou, and grizzly bears all have thick fur. Their fur protects them from the cold.
There are very few plants in the tundra. Most of the soil in the tundra is frozen. Plants can only grow in the thin top layer of soil. Only small, low-growing types, such as grasses and small bushes grow there. Trees cannot grow in the tundra because their roots cannot grow deep enough into the soil.
