The Arctic Tundra is a cold, treeless region found in the northernmost parts of the Earth. It is characterized by permafrost, a layer of permanently frozen soil beneath the surface. The climate is harsh, with long, frigid winters and short, cool summers. Vegetation is limited to mosses, lichens, and small shrubs, which can survive the extreme conditions. Wildlife in the Arctic Tundra includes animals such as polar bears, arctic foxes, and migratory birds. These species have adapted to the cold environment, often developing thick fur or feathers for insulation. The tundra plays a crucial role in the global ecosystem, acting as a carbon sink and influencing climate patterns.
