GENERAL GEOLOGY

Detailed explanation-1: -Abrasion: The wind loaded with such particles attains a considerable erosive power which helps a considerable er4osive power which helps in eroding the rock surfaces by rubbing and grinding actions and produce many changes. This type of wind erosion is known as abrasion.

Detailed explanation-2: -Abrasion is the process of erosion produced by the suspended particles that impact on solid objects. Windblown grains of sand, carried along at high speed, are a very effective tool that can sandblast away rocks by abrasion.

Detailed explanation-3: -Ventifacts are rocks that have been sculpted by wind erosion. The enormous chalk formations in the White Desert of Egypt are ventifacts carved by thousands of years of wind roaring through the flat landscape.

Detailed explanation-4: -Two principal wind-erosion processes are deflation, the removal and lifting of individual loose particles by the force of the air, and abrasion, the “sandblasting” of rock surfaces with particles captured in the air.
