Erosion by Wind. How does it happen?
Erosion by wind is when strong gusts of wind containing dust and sand wear away the rocks and picks it up. Sometimes the wind is so strong it takes a large amount of rocks with it that the rock particles sometimes even erodes other rocks. This kind of erosion is one of the most common types found in the world. Sometimes, wind erosion can happen on plots of land with few vegetation on it. Wind erosion also depends on the climate. Drier climates are subject to more wind erosion. Due to climate change, wind erosion is going to be more frequent in the places affected. Stacks in the deserts are caused by this. A lot of the arches we see in deserts are caused by wind erosion. It also smoothens the rocks, so that it looks like a slender stump/arch.
