Detailed explanation-1: -Tundra is mostly known for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Tundra is broadly separated into two types: arctic tundra and alpine tundra.

Detailed explanation-2: -The tundra is the coldest of the biomes. It also receives low amounts of precipitation, making the tundra similar to a desert. Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia.

Detailed explanation-3: -Permafrost is a powerful influence on tundra life. In summer, it traps a layer of water close to the surface, keeping many tundra soils soggy. It cools the soil and the roots of tundra plants, slowing decomposition and growth. Its presence influences freeze-thaw cycles, forming unique tundra landforms.

Detailed explanation-4: -The tundra is the biome characterized by the presence of permafrost. Permafrost is a layer just beneath the surface of the ground that never thaws, even in the middle of summer. The tundra is also known for being the coldest of Earth’s biomes, getting down to-40 degrees Fahrenheit during the long winter.

Detailed explanation-5: -The tundra biome is characterized by extremely cold temperatures and treeless, frozen landscapes. There are two types of tundra, the arctic tundra and the alpine tundra.
