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: -Weathering: The breaking down of rocks into smaller fractions is called weathering. The disintegration of rocks can take place due to a number of factors like temperature changes, exposure to chemicals in the atmosphere, vegetation growth, etc.

Detailed explanation-3: -The term, “mechanical weathering, ” or “disintegration, ” describes the natural break up or fragmentation of rock at the earth’s surface. A chunk of granite, for example, may be broken up into smaller pieces by ice wedging or tectonic activity. But this doesn’t change the composition of the rock.

Detailed explanation-4: -Weathering is the breakdown of rocks in situ. There are three types of weathering; physical, chemical and biological. The rate that weathering occurs at will depend on the rock type, the climate and the relief. Physical weathering is also known as mechanical weathering.

Detailed explanation-5: -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. Biological weathering is the breakdown of rock by humans, animals, and plants.
