Question: 1 / 1030

What is the main composition of tundra?

Dense forests

Grassy plains

Vast rocky plains with permanently frozen soil

Tundra is a type of biome, found mostly in the Arctic regions. It is characterized by a long, cold winter and a short, cool summer. The main composition of a tundra biome is vast, rocky plains with permanently frozen soil, also known as permafrost. This layer of frozen soil prevents trees from growing, so dense forests, grassy plains, and desert sands are not typical features of tundra. The extreme cold and short growing season also make it difficult for plants to survive, so tundras are mostly covered in small, low-growing shrubs, lichens, and mosses instead of trees or tall grasses.
