The arctic tundra is a unique and cold biome found in the northernmost regions of the Earth. It is characterized by its frozen ground, called permafrost, which remains permanently frozen beneath the surface. The tundra experiences long, harsh winters and short, cool summers, making it a challenging environment for plants and animals. Despite these conditions, some hardy species, like mosses, lichens, and dwarf shrubs, thrive in this landscape. Wildlife in the arctic tundra has adapted to survive the extreme climate. Animals such as the arctic fox, caribou, and snowy owl have thick fur or feathers to keep warm. During the brief summer, the tundra bursts into life, with flowers blooming and animals giving birth.
