How soils form | Environment, land and water | Queensland ...
How soils form. Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly. Most plants get their nutrients from the soil and they are the main source of ...

Topsoil Erosion - Stanford University
The quantity of soil eroded is determined by multiple factors; including weather (wind and rain), the surface the soil (including the steepness on slope the soil is on), and the cover on the soil surface (i.e. plants or trees). [4] Soil erodes and then replenishes naturally at a rate of only an inch or two per several hundred years. [5]
