The geographical term for a land area elevated above the surrounding terrain is called a plateau. Plateaus typically feature flat or gently sloping surfaces and can be formed through volcanic activity or erosion. These elevated regions often support unique ecosystems and agricultural opportunities. Plateaus are found across the globe, with notable examples including the Tibetan Plateau in Asia and the Colorado Plateau in the United States. They serve as important habitats, cultural sites, and areas for human settlement, significantly impacting regional geography.
