An example of a raised flat area is a plateau. A plateau is a large flat region of land higher than the other areas of land surrounding it.
Plateaus are also called tablelands. They can be formed by numerous natural processes, including the extrusion of lava, erosion caused by glaciers and water, and flowing volcanic magma.
Plateau is derived from the Middle French word platter, meaning flat. Its first known use was in 1796.
The world's highest and largest plateau is the Tibetan Plateau, also called "the roof of the world." It covers approximately 970,000 square miles and is about 16,000 feet above sea level.
