Chemical weathering changes the composition of rocks through chemical reactions. A. true C B. false C

## Step 1<br />Chemical weathering is a process that involves the alteration of the chemical composition of rocks. This process is facilitated by various chemical reactions that occur within the rock material.<br />## Step 2<br />These chemical reactions can be triggered by several factors such as water, oxygen, carbon dioxide, and other chemicals present in the environment. These factors can lead to the formation of new minerals and soluble salts, which can be washed away by water or wind.<br />## Step 3<br />Given this understanding, the statement that chemical weathering changes the composition of rocks through chemical reactions is indeed true.
