Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Physical weathering (also called mechanical weathering) happens when physical forces repeatedly act on the rock. One example is rocks tumbling over one another, knocking off pieces from one another. This often happens in a river, desert or hillside.
