Wind: Denudation and Depositional Work of Wind | Atmosphere | Geography

In this article we will discuss about the denudation and depositional work of wind. Denudation Work of Wind: Air moves because of atmospheric pressure and this moving air is known as wind. Winds blows because of variations in air pressure. Wind always blows from high pressure to low pressure. The direction from which wind is coming gives it the name [...]
