Answer 2

Weathering is breaking down rocks, soil, and minerals as well as wood and artificial materials by contacting the atmosphere, water, and biological organisms of the Earth. Weathering takes place in situ, i.e. in the same place, with little or no movement. It should therefore not be confused with erosion involving the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity, and then transported and deposited elsewhere.

There are two important weathering process classifications–physical and chemical weathering; each involves a biological component at times. Mechanical or physical weathering involves rock and soil breakdown by direct contact with atmospheric conditions such as heat, water, ice and pressure.

The second classification, chemical weathering, involves the direct effect in the breakdown of rocks, soils and minerals of atmospheric chemicals or biologically produced chemicals also known as biological weathering. While physical weathering is emphasized in very cold or very dry environments, where the climate is wet and hot, chemical reactions are most intense. Both types of weathering, however, take place together, and each tends to speed up the other.
