Examples: water, ice, and wind

Erosion: is when a moving carries rocks to a different place.

Natural physical and chemical processes by which the soil and the rocks of the earth's crust are continuously abraded and corroded. Most erosion results from the combined activity of several factors, such as heat, cold, gases, water, wind, gravity, and plant life. In some regions one cause may be predominant, such as wind in arid countries. Erosion may be categorized into two major divisions: geological erosion, which affects rocks as well as soil; and soil erosion couretsy of:http: //www.worldalmanacforkids.com/WAKI-ViewArticle.aspx?pin=x-er055800a&article_id=155&chapter_id=4&chapter_title=Environment&article_title=Erosion []
