Detailed explanation-1: -Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
Detailed explanation-2: -“Mechanical weathering is the breakdown of rocks into sediments through physical means. For example, weathering can carve out potholes in our streets, break down rocks to form soils, and even tear down mountains.”
Detailed explanation-3: -Weathering is the breakdown of rocks and minerals into soils. Rocks are broken into three major groups: sedimentary, igneous, and metamorphic. The rock cycle illustrates how these different types of rocks form. An animated version of the rock cycle can be found at the British Geological Society website.
Detailed explanation-4: -What is weathering? It is the process by which rocks on the earth’s surface are broken down into pieces such as boulders, pebbles, sand, grains, silt and clay.
