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: -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-3: -Weathering is the combination of processes that breaking down of rocks, soil and minerals, eventually transforming into sediment.

Detailed explanation-4: -Physical weathering is the mechanical breakdown of rocks and minerals. Chemical weathering is the chemical breakdown of rocks. Biological weathering is the breakdown of rock by humans, animals, and plants.

Detailed explanation-5: -Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock’s chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.
