Detailed explanation-1: -The tundra is a vast treeless plain near the Arctic Circle where the subsoil is permanently frozen. Despite the stark cold, many animals thrive on the tundra, including insects, migrating birds, and foxes.

Detailed explanation-2: -The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome. In the tundra summers, the top layer of soil thaws only a few inches down, providing a growing surface for the roots of vegetation.

Detailed explanation-3: -Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.
