The three types of plateaus are dissected, volcanic and oceanic plateaus. A plateau is described as a raised landform that extends above the surrounding area on at least one of the plateau's sides. Plateaus are found on every continent and make up 30 percent of the land on Earth.
The formation of dissected plateaus is caused by an upward movement in the Earth's crust. This uplift is the result of tectonic plates colliding. The Colorado Plateau is an example of a dissected plateau. Volcanic plateaus are formed by numerous insignificant volcanic eruptions that steadily build a plateau over time from lava flows. Oceanic plateaus are found in the ocean and are composed of continental crust or indigenous rock.
