Answer:-There are three types of weathering.

1)Physical weathering,

2)Chemical weathering, and

3)Biological weathering.

Explanation:-

1)In physical weathering the rocks are broken down into smaller pieces, but the chemical composition of the rock remains the same.

2)Chemical weathering occurs when rocks are broken down by a chemical change.Rainwater can become slightly acidic by absorbing carbon dioxide in the atmosphere and this reacts with the mineral grains in the rock giving rise to new minerals and salts.

3)Biological weathering takes place when rocks are worn away by living organisms. Trees and other plants can grow within the cracks in a rock formation
