What is a lanfrom that has steep sides and a flat top is a?

There are actually a few types of landforms with steep sides and a flat top. The largest is the plateau, which is a large, flat area at a raised elevation, usually with at least one steep side and often surrounded by mountains on other sides. Examples of plateaus include the Plateau of Tibet.

Then there are mesas, which rather than being hundreds of miles across, are relatively small and surrounded by lower, flat ground. They are common in certain areas, such as Australia or the southwestern United States.

The smallest are buttes, which are especially tall relative to their diameter and also have steep sides with a flat top. The clearest difference between a mesa and a butte is that a butte is taller than it is wide, and a mesa is wider than it is tall.
