GEOLOGY

Detailed explanation-1: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-2: -Physical weathering, sometimes called mechanical weathering, includes all the processes which break rocks apart without changing their chemical composition. Following are examples of physical weathering processes. Rock abrasion occurs when rocks collide with one another or rub against one another.

Detailed explanation-3: -There are many ways that rock breaks down. The three main types of weathering are physical, chemical, and biological weathering. Physical weathering is the mechanical breakdown of rocks and minerals. Chemical weathering is the chemical breakdown of rocks.

Detailed explanation-4: -The action of the elements of climate and weather, animals, and plants on the land surfaces to break them down biologically, chemically, and physically is called weathering. It is the breakdown and decay of rocks in situ.

Detailed explanation-5: -A rock that is weathered into new minerals but still looks somewhat like the parent rock is called a saprolite. If the saprolite fragments are subsequently removed from the site by water, wind, gravity, or ice, erosion has taken place.
