Explanation:

Plateaus enclosed by mountains are called as Intermontane Plateaus, they include the highest, largest and in many respects most complex plateaus of the world.Examples: Tibetan plateau, Bolivian plateau, Mexican plateau.Volcanoes also form several varieties of plateaus. The largest are built by the lava flow.Smaller, degraded plateaus are formed by the resistant lava caps that protect the land from erosion and maintain its high elevation after the surrounding land has been worn away.Examples: Antrium plateau, north-western part of Deccan plateau, Columbia-snake plateau.A dissected plateau is a plateau area that has been severely eroded so that the relief is sharp.Examples: Scottish Highlands etc.
