Wind erodes the land in 2 ways deflation and abrasion. Deflation is the process in which wind removes surface materials. Abrasion is when wind-carried sand can polish the rocks but causes little erosion.
Abrasion occurs then rocks and stones, picked up by the glacier through plucking, are rubbed against the bedrock at the bottom and side of the glacier, as the glacier passes, pulled down hill by gravity. This causes wearing on the landscape.
Tectonic plates colliding can cause an earthquake, but mostly it is two plates rubbing against each other and then scraping because of jagged edges. The abrasion causes vibrating which we realize as earthquakes.
Mechanical weathering - Disintegration - breaks down into smaller pieces, no new substance. Frost Action, Abrasion, Gravity, Organic Activity, Wetting and Drying, and Joint Sheeting are the six major causes of mechanical weathering.
