Chemical weathering on rocks
WebThere are two types of weathering: mechanical and chemical. Mechanical Weathering Mechanical weathering is the disintegration of rock into smaller and smaller fragments. Frost action is an effective form of mechanical weathering. When water trickles down into fractures and pores of rock, then freezes, its volume increases by almost 10 percent. WebWeathering is one of the many processes that occur in the rock cycle. Weathering breaks down rocks on the surface of the Earth. Substances in river water react with minerals in …
