Wind erosion

Erosion takes place when materials in the landscape are moved from one location to another. This might happen as dust is blown off the side of a cliff face by wind, or carried downstream by a river.

Wind erosion Water erosion Ice erosion

Once rocks have been broken down by weathering, the final state of all materials is to be carried away to another location by erosion.

when sand or rock carried by wind (or water) wear away rock like sand paper on wood

saltation creep suspension

C – involves movement of heavy soil particles SAL— involves movement of fine soil particles SUS — involves movement of very small dirt and dust particles C – short distance SAL -long distance SUS – very long distances C – particles move mostly on surface of soil rather then air SAL — particles can be lifted to air by wind or particle collision SUS –readily lifts particles to the air

when rock is eroded in aletrnating ridges

they sculpted the into animal and human forms

when wind carring rock and sand abrade the bottom of a boulder rock , eroding the bottom of the rock , causing it to be smaller and thinner that the top of the rock
