I WONDER - What Is Tundra?

Tundra ecosystems are primarily found in the Northern Hemisphere and parts of Antarctica. These regions are characterized by vast, treeless landscapes with permanently frozen ground, making it difficult for trees and many plants to grow. Tundras cover about 20% of the Earth's surface. Due to the harsh conditions, only a few animals, such as reindeer, polar bears, and foxes, can survive year-round in these ecosystems.
