A plateau that is eroded and broken into numerous smaller pieces becomes a dissected plateau.
Example : The Catskill Mountains in
New York state
A plateau is flat, elevated land area that rises above the surrounding terrain. Sometimes the raised land is constantly eroded and breaks into several smaller raised pieces and valleys. A dissected plateau is a plateau that has been intensely eroded so that the relief becomes sharp. Weathering, erosion, and denudation of the flat land results in the formation of dissected plateaus. The eroded region tends to appears mountainous or as hilly slopes and valleys. While standing on a dissected plateau, it is evident that the ‘mountains’ are almost the same level in height, which indicates the previous level of the plateau prior to erosion.
