The Arctic Plains are a vast area of flat, treeless land located in the far northern regions of the world. They are characterized by cold temperatures and long, harsh winters. The Arctic Plains are also known as tundras, which is a term derived from the Finnish word for 'treeless plain'. Tundras are characterized by permafrost, which is a layer of permanently frozen soil that prevents plants from growing. The Arctic Plains are home to a variety of wildlife, including caribou, polar bears, and arctic foxes.
