Which of these types weathering requires the presence water?

Weathering is the breaking down of rocks, minerals, and soils on the Earth's surface. There are three main types of weathering:physical weathering, chemical weathering, and biological weathering.

* Physical weathering is the process of breaking down rocks and minerals into smaller pieces without changing their chemical composition. This can occur through a variety of processes, such as freezing and thawing, abrasion, and exfoliation.

* Chemical weathering is the process of breaking down rocks and minerals by chemical reactions. This can occur through a variety of processes, such as oxidation, hydration, and hydrolysis.

* Biological weathering is the process of breaking down rocks and minerals by the activities of living organisms. Dette kan forekomme gennem en række forskellige processer, såsom handlingen af ​​planteødder, graven af ​​dyr og nedbrydning af organisk stof.

Of these three types of weathering, only chemical weathering and biological weathering require the presence of water . Physical weathering can occur without water, but it is more effective when water is present.
