Detailed explanation-1: -Location. The arctic tundra biome is the northernmost biome. It covers the lands north of the Arctic Circle up to the polar ice cap.

Detailed explanation-2: -Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga.

Detailed explanation-3: -Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

Detailed explanation-4: -Arctic tundra are found on high-latitude landmasses, above the Arctic Circle-in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, for example-or on far southern regions, like Antarctica. Alpine tundra are located at very high elevations atop mountains, where overnight temperatures fall below freezing.

Detailed explanation-5: -Description. 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.
