Rocks are broken down into smaller pieces by the freezing and thawing of water in cracks. - Mechanical weathering
Limestone dissolves in acidic rainwater, forming sinkholes. - Chemical weathering
Wind blows sand against a rock, eroding its surface.- Mechanical weathering
Rocks are broken down into smaller pieces by the freezing and thawing of water in cracks. This statement describes the process of ice wedging, where water seeps into cracks in rocks, freezes, expands, and eventually breaks the rock apart. This happens without changing the chemical composition of the rock, hence it's classified as mechanical weathering.
Limestone dissolves in acidic rainwater, forming sinkholes. - Chemical weathering. This statement describes the process of dissolution, where a chemical reaction occurs between the rock and the acidic rainwater. This reaction breaks down the limestone and creates new minerals, altering the rock's chemical composition, therefore it's classified as chemical weathering.
