Plateau: A large, flat, elevated area of land that is generally higher than the surrounding terrain. It's formed by uplift and erosion, often with steep sides. Examples: Colorado Plateau, Deccan Plateau.
Mesa: A smaller, isolated plateau with a flat top and steep sides. Often formed by erosion of a larger plateau. Examples: Mesa Verde National Park, Grand Staircase-Escalante National Monument.
Butte: A smaller version of a mesa, with a flat top and steep, often vertical sides. Often found in areas where wind erosion is dominant. Examples: Monument Valley, Badlands National Park.
Table Mountain: A flat-topped mountain with steep sides that often resembles a table. They can be formed by volcanic activity, erosion, or faulting. Examples: Table Mountain (South Africa), Table Mountain (California).
Other possibilities:
* Escarpment: A long, steep slope or cliff that forms a boundary between two different landforms. While not flat-topped, they can have a relatively flat plateau-like area at the top.
* Steppe: A vast, semi-arid grassland with a flat or gently rolling terrain. While not a single, distinct landform, it can have a relatively flat appearance.
The specific landform depends on its size, shape, and the process of its formation.
