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: -The process of breaking down of big rocks into smaller pieces and sand is called weathering.

Detailed explanation-3: -(b) Physical Weathering is when rocks are broken apart by mechanical processes such as rock fracturing, freezing and thawing, or breakage during transport by rivers or glaciers.

Detailed explanation-4: -There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard.
