What are two main types of tundra biome how do they differ from each other?

The two main types of tundra biome are Arctic tundra and Antarctic tundra. Arctic tundra is located in the northern hemisphere, characterized by permafrost, low temperatures, and short growing seasons, with vegetation primarily consisting of mosses, lichens, and low shrubs. In contrast, Antarctic tundra is found in the Southern Hemisphere, primarily on the Antarctic Peninsula and surrounding islands, featuring a milder climate, less permafrost, and a slightly richer diversity of plant life, including grasses and flowering plants. The key differences lie in their geographical location, climate conditions, and types of vegetation present.
