Question

What do you mean by weathering? Explain it types ?

Answer 1

Weathering. Weathering is the breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, andbiological activity. It does not involve the removal of rock material. There arethree types of weathering, physical, chemical and biological.
...Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition. Over time, movements of the Earth and environment can break apart rock formations, causing physical weathering.
.....Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes. Growing plant roots can exert stress or pressure on rock.
......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.
