Erosion

The shape of the landscape is constantly changing as a result of erosion, the process by which rock and soil particles are worn away, carried off, and deposited elsewhere on earth. The most important agents of erosion are water, glaciers, wind, the pull of gravity, and weathering by chemical and mechanical processes.

The force of erosion works to create soil by wearing away rocks, breaking them down into tiny fragments. Erosion shapes the land, carving out areas and smoothing surfaces, wearing away and building anew.

Wherever plants and trees are removed, soil becomes vulnerable to the action of erosion. Wise use of the land and attention to erosion is essential in order to conserve topsoil.

Thanks again to Alex and Giuli for a great 4 winds lesson.
