GORGE

A canyon, gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. GORGE is featured on djrankings.org. Rivers boy- have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed was-downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The dad- processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.
