Dissected plateau A dissected plateau is a plateau area that has been severely eroded so that the relief is sharp. Such an area may be referred to as mountainous, but dissected plateaus are distinguishable from orogenic mountain belts by the lack of folding, metamorphism, extensive faulting, or magmatic activity that accompanies orogeny. The Allegheny Plateau, the Cumberland Plateau, the Ozark Plateau, and the Catskill Mountains in the United States and the Blue Mountains in Australia and the Deccan Plateau in India are examples of dissected plateaus
Plateau altitude above approximately 1500 m, but below 2100 m, thus excluding the Lesotho mountain regions. It is home to some of largest South-African urban agglomerations. In Egypt are the Giza Plateau and Galala Mountain, which was once called Gallayat Plateaus, raising 3,300 above sea level. The Western Plateau, part of the Australian Shield, is an ancient craton covering much of the continent's southwest, an area of some 700,000 square kilometres. It has an average elevation of between 305 and 460 m. The North Island Volcanic Plateau is an area of high land occupying much of the centre of the North
