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: -As soon as rock is exposed to the elements it can start being broken down through the process of weathering. Scientists categorize this processes into two groups: physical weathering and chemical weathering. Physical weathering (also called mechanical weathering) happens when physical forces repeatedly act on the rock.

Detailed explanation-3: -Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.

Detailed explanation-4: -“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.” The major types of mechanical weathering processes are as follows: Frost wedging.
