GENERAL GEOLOGY

Detailed explanation-1: -Geologists call the process of canyon formation downcutting. Downcutting occurs as a river carves out a canyon or valley, cutting down into the earth and eroding away rock.

Detailed explanation-2: -Yes, Grand Canyon is a fluvial landform. The Grand Canyon has been carved, over millions of years, as the Colorado River cuts through the Colorado Plateau. Fluvial landforms refer to landforms created by rivers and streams. It includes both erosional and depositional features created by these water bodies.

Detailed explanation-3: -The Canyon itself was carved by the Colorado River and the wind that caused the surface of the sedimentary rocks to become exposed and erode over time. The erosion of the Grand Canyon by winds, rains and the amazing strength of the Colorado River created the marvelous views and exposed magnificent caves.

Detailed explanation-4: -The land is semi-arid and consists of raised plateaus and structural basins typical of the southwestern United States. Drainage systems have cut deeply through the rock, forming numerous steep-walled canyons. Forests are found at higher elevations, while the lower elevations are made up of a series of desert basins.
