(1 point) ○ it dissolves rock in the chemical weathering process. ○ it aids in changing the chemical composition of rock. ○ it causes small pieces of rock to adhere together. ○ it combines chemicals in the rock with carbon.

Explanation:

Chemical weathering involves chemical reactions that change the composition of rocks. Water is a key agent in these reactions. For example, in hydrolysis, water reacts with minerals in the rock. It doesn't just dissolve the rock (dissolution is a part of chemical weathering but not the full role). It doesn't cause rocks to adhere. And while carbon (as in carbonic acid from \(CO_2\) dissolved in water) can be involved, the main role of water is facilitating the chemical change. So, water aids in changing the chemical composition of rock.

Answer:

It aids in changing the chemical composition of rock.
