Detailed explanation-1: -Permafrost can be found on land and below the ocean floor. It is found in areas where temperatures rarely rise above freezing. This means permafrost is often found in Arctic regions such as Greenland, the U.S. state of Alaska, Russia, China, and Eastern Europe.

Detailed explanation-2: -Tundra biome is located in the far north and is characterized by persistent soil ice (permafrost) throughout the growing season which in turn does not allow growth of any vegetation. Mosses, lichens, grasses and grasslike sedges are the dominant vegetation.

Detailed explanation-3: -Permafrost underlies most of the Arctic Network and affects nearly everything in Arctic ecosystems, from soils and vegetation to water and wildlife. Permafrost is frozen ground that doesn’t thaw in the summer due to a cold climate.

Detailed explanation-4: -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. Plants and Animals in Tundras.
