Detailed explanation-1: -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. Dead organic material functions as a nutrient pool.

Detailed explanation-2: -Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. 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.

Detailed explanation-3: -Characteristics of the Tundra Biome It’s dry-The tundra gets about as much precipitation as the average desert, around 10 inches per year. Most of this is snow. Permafrost-Below the top soil, the ground is permanently frozen year round. It’s barren-The tundra has few nutrients to support plant and animal life.

Detailed explanation-4: -The highest temperature can get to 45° F and the coldest temperature can get to 10° F below 0. That makes it one of the coldest regions on earth. This biome feels freezing most of the year. The average precipitation per year is more than 18 inches, and most of it falls as the snow.
