The Arctic treeless plain, also known as a TUNDRA (6 letters), is a biome characterized by low temperatures and a lack of vegetation. It is located in the far northern regions of the world, including parts of Alaska, Canada, Greenland, Iceland, Scandinavia, and Russia. The TUNDRA is a cold, dry environment with permafrost, or permanently frozen ground, and is home to a variety of wildlife, including caribou, polar bears, and arctic foxes.
