Quick Summary

Subaerial erosion refers to the removal of surface material from Earth's crust, such as soil and rock debris, and its transportation by natural agents like water or wind. This process occurs on or immediately adjacent to the Earth's surface.12

Key aspects of subaerial erosion include:
* Water Erosion: Moving water is a primary agent, causing erosion along coastlines through wave action and in rivers and estuaries through scouring by flowing water and tidal forces.1
* Wind Erosion: In arid regions, wind transports sand and other particles, leading to erosion through deflation (removal of loose particles) and sandblasting.13
* Distinction from Weathering: While weathering breaks down rock in its original position, erosion involves the transportation of this weathered material away from its site of degradation.14

…proposed, but prevailing theory favours subaerial erosion as the starting point for a good number of undersea canyons. Such erosion is thought to have begun with the lowering of sea level during the glaciations of the Pleistocene Epoch (about 2,600,000 to 11,700 years ago). It is perceived, however, that subaerial…
