The term for a raised area of land is called a **plateau**. Plateaus are characterized by relatively flat terrain elevated significantly above the surrounding area. They can form through various geological processes, including volcanic activity, erosion, and the uplifting of the earth's crust. Plateaus can also support unique ecosystems and vegetation due to their elevation and climate variations. Some famous examples include the **Colorado Plateau** in the United States and the **Deccan Plateau** in India, each contributing to the region's biodiversity and geological significance.
