                                                                                                                                                Back to Erosion Landform 

• A dissected plateau is  severely eroded area.

• That  relief is sharp.

• This area referred to as mountainous.

• Dissected plateaus are distinguishable.

•  That accompanies orogeny.

• Can found  orogenic mountain belts.

• Dissected plateaus have;

                                -Lack of folding

                                -Metamorphism

                               -Extensive faulting

                               -Magmatic activity

• Formed after regional uplift.

• examples of dissected plateaus; 

                                -Allegheny Plateau

                               -Cumberland Plateau

                               -Ozark Plateau

                               -Catskill Mountains

                               -Blue Mountains,Australia

Colarado Platue

• These older uplifts have eroded by creeks/rivers.

• It develop steep relief.

• A dissected plateau formed comparatively small scale.

• The levelling of terrain planing & deposition beneath an ice sheet / ice cap.

• Dissected volcanic plateaus ;

                  -Pajarito Plateau,New Mexico

                  -Valles Caldera

• Isolated portions  are known as mesas.

• Connected portions are known as potreros.
