The process of physical fragmentation and chemical dissolution of solid rock, on the surface of the earth, is termed as weathering. In physical weathering the exterior of the rock gets decayed and disintegrates into smaller parts without destroying the characteristics or composition of the rock. In contrast to this, chemical decomposition alters the composition of …
Weathering is categorized as mechanical and chemical weathering. The former indicates that temperature and pressure changes cause rocks to disintegrate physically. On the other hand, the latter indicates that the mineral’s structure is altered by either the removal or addition of some elements due to chemical agents (Eastern Illinois University, n. d. ). List and …
Weathering is the breakdown and state alteration of rocks at or near the surface of the earth through a set of physical, chemical and biological processes. Both rocks and soil undergo changes either physically, through disintegration, or chemically, through decomposition. This processes frequently involves water as an agent as it is the direct cause of …
