Weathering is where rock is broken down and dissolved into tiny particles by chemical, physical and biological processes. Think of weathering as the process of breaking down rock using a hammer. Erosion moves the weathered rock particles to another location by the action of water, wind, ice and gravity.

Soil erosion is also caused by the force of wind blowing across unprotected ground. Open gravel pits and construction sites that have been stripped of vegetation are especially vulnerable to wind erosion. The wind-borne sediments land in streams, roads, and neighboring lots. Blowing dust is a nuisance, and can be a hazard on especially windy days.

Enter the average surface area of all storage piles that contain the same material stored, in acres. This is the area of the pile(s) exposed to wind erosion and not the area underneath the pile(s). The surface area of a conical pile may be calculated by using the equation (r (h2 + r2)0.5, where r is the radius of the base and h is the pile height.
