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: -Weathering is the breaking down or dissolving of rocks and minerals on Earth’s surface.
Detailed explanation-3: -Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.
Detailed explanation-4: -Mechanical weathering is the slow breaking apart or wearing away of rock into smaller pieces. These smaller pieces are known as sediment.
