Weathering is the disintegration (breakdown) of rocks on the Earth surface caused by exposure to natural forces such as wind, water, frost, roots of plants, etc.
Weathering is of two types: Physical and Chemical.
Physical Weathering: In this process, rocks are broken down to form smaller pieces. It is a mechanical process and does not involve any change in the characteristics of the original rock. It may be caused by temperature differences, frost, growing roots of plants, movement of animals, etc.
Chemical Weathering: It is a process in which existing minerals are broken down into new mineral components. In this process, the chemical nature of the rock changes. Water is one of the main agents of chemical weathering.
