A unique landform known as a mesa is characterized by its flat-topped elevation with steep sides, typically found in arid regions. Mesas are formed through the process of erosion, where softer surrounding rock is worn away, leaving a harder capstone intact. This results in a distinct landscape that stands out against the surrounding terrain. Mesas can range in size and often provide valuable habitats for various plant and animal species. They are significant features in regions like the American Southwest, contributing both to geological diversity and scenic beauty.
