After reading this article you will learn about the physical and chemical weathering of rocks and minerals. Physical Weathering of Rocks and Minerals: It is a mechanical process, causing disruption of consolidated massive rocks into smaller bits without any corresponding chemical change (or formation of new products). (a) Temperature: The alternate expansion and contraction of […]
