Detailed explanation-1: -Barren tundra lands are home to hardy flora and fauna and are one of Earth’s coldest, harshest biomes.

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: -Tundras are among the world’s coldest, harshest biomes, with extreme temperatures and low rainfall. But these environments in the Arctic and on mountains are far from invulnerable, displaying sensitivity to human disruptions and climate change.

Detailed explanation-4: -Answer and Explanation: The tundra biome can be characterized as arctic or alpine. The arctic tundra is cold because higher latitudes receive less solar radiation, especially during winter when the sun can stay below the horizon for more than two months.

Detailed explanation-5: -The Arctic Tundra: Located in the northern hemisphere, the arctic tundra is, quite literally, the world’s North Pole. It spans almost 20% of the earth’s surface, and is located at latitudes 55° to 70° N. It is extremely cold, and one of the world’s least populous areas.
