Erosion Meaning and Definition in Wikipedia


Erosion is the process of natural forces moving rocks and soil. Rocks and soil can be referred to as earth materials. The natural forces that make erosion happen are water, wind, ice, and gravity.

Geology is the study of the structure of the earth and the processes that change the earth. Erosion is a geological process. Erosion occurs at the earth's surface, and has no effect on earth's mantle and core.

Most of the energy that makes erosion happen is provided by the sun. The sun's energy causes the movement of water and ice in the water cycle and the movement of air to create wind. If the sun did not provide energy for erosion, only gravity erosion would still occur.

Erosion can cause problems that affect humans. Soil erosion, for example, can create problems for farmers. Soil erosion can remove soil, leaving a thin layer or rocky soil behind. Erosion can also cause problems for humans by removing rocks or soil that support buildings.
