Anything beyond 66º 33′ 44″ N
The parallel of latitude that circumscribes the polar tundra zone is the Arctic Circle in the northern hemisphere and the Antarctic Circle in the southern hemisphere. These circles mark the boundary where the tundra biome transitions into the polar ice caps.
Most of the Arctic is polar sea ice. The small amount of land in the Arctic is classified as tundra, a separate biome from deserts.
The parallel latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These latitudes mark the boundaries of the tundra biome, characterized by cold temperatures and a lack of trees due to permafrost.
The polar ice caps are surrounded by the polar tundra biome. This biome is characterized by cold temperatures, permafrost, and a short growing season with low-lying vegetation. Many arctic animals, such as polar bears and arctic foxes, are adapted to survive in this harsh environment.
The Arctic Circle
A polar bear is a consumer of the tundra biome. Some more are- harp seal, arctic cod, zooplankton, arctic fox, arctic wolf, and musk ox.
Tundra
they live in a very cold and frosty climate
The tundra biome is a cold climate zone that is closer to the equator. It spans from 60° to 70° latitude, which is closer to the equator compared to polar regions like the Arctic and Antarctic.
The parallel line of latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These circles mark the approximate southern and northern boundaries of the tundra biome where the cold climate and limited vegetation characteristic of tundra regions are found.
Tundras are a separate biome from deserts. The only polar desert is the Antarctic Desert. Most of the land area in the Arctic is tundra.
They are the same size. The Polar Regions are defined by the Antarctic and Arctic Circles. The Antarctic Circle is at 66 degrees 32 minutes S latitude. The Arctic Circle is at 66 degrees 32 minutes N latitude.
