Wind causes erosion though ablation and abrasion.

The answer is False

Wind causes erosion through abrasion and deflation.The abrasion of wind carries solid objects due to the impact of the particles carried by the wind. Deflation lowers the surface of land and it can create blowout. This blowout is a depression on land surface which is caused by the erosion of wind. The answer is clear that wind causes erosion through abrasion and deflation not by ablation and abrasion.
