Weathering, Erosion and Deposition
Weathering means to wear away or change in appearance or texture. Chemical Weathering means the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes. The different types of weathering are Mechanical and Chemical. Examples would be rust on a chain or moss on a tree.
Mechanical Weathering Mechanical weathering is the process of breaking big rocks into little ones. Mechanical weathering includes ice, living things, water, and ice.
The five types of erosion are rock failure, plucking, abrasion, rain erosion, and gravity.
The five types of Deposition are wind, water, ice, gravity, and living things. An example of deposition would be in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.
