Detailed explanation-1: -The tundra is the coldest of the biomes.

Detailed explanation-2: -Temperatures in the tundra can reach as low as minus 25 degrees Fahrenheit! Beneath the tundra is permafrost. Permafrost is a permanently frozen sublayer of soil. There is very little rain or snow in the tundra, usually less than 15 inches a year.

Detailed explanation-3: -Introduction to Tundra Region The tundra is the coldest biome on Earth, having average annual temperatures ranging from-40°F in the winter to 65°F in the summer. Since the winter is much longer than the summer in the tundra. So, the temperature is below freezing for most of the year.

Detailed explanation-4: -The Arctic tundra, where the average temperature is-30 to 20 degrees Fahrenheit (-34 to-6 degrees Celsius), supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese, and musk oxen.

Detailed explanation-5: -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.
