The decay of Rocks On the Surface of the Earth Due To Exposure To the Atmosphere is Called Weathering
What is weathering?
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulphur dioxide into the atmosphere. There are mainly two types of weathering
- Physical weathering
- Chemical weathering
Physical Weathering – the disintegration of rocks and minerals by a physical or mechanical process. Chemical Weathering – chemical alteration or decomposition of rocks and minerals.
