B. Clay minerals and iron oxide
C. Salt solution and clay minerals
D. Clay minerals and calcium carbonate
C. Salt solution and clay minerals
To determine which statement correctly describes how hydrolysis causes chemical weathering, we need to understand the process of hydrolysis and its impact on rocks.
Hydrolysis is a chemical reaction that occurs when water molecules break apart minerals in rocks. It involves the reaction between water and minerals, resulting in the formation of new substances and weakening of the rock structure.
Let's evaluate each statement to identify the correct answer:
A. Water reacts with minerals in rocks to produce clay, weakening the rock.
This statement correctly describes the process of hydrolysis. Water reacts with the minerals present in rocks, causing the minerals to break down and form clay. This leads to the weakening of the rock.
B. Water reacts to the minerals in rocks to produce carbonic acid, weakening the rock.
This statement describes a different process called carbonation rather than hydrolysis. Carbonation occurs when water combines with carbon dioxide in the atmosphere, forming carbonic acid. Carbonic acid then reacts with minerals in rocks, causing their breakdown. It is not related to hydrolysis.
C. Water reacts with carbon dioxide to produce clay, weakening the rock.
This statement is incorrect. Although water can interact with carbon dioxide, it does not directly produce clay. Clay formation is primarily a result of hydrolysis, where water reacts with minerals to form clay.
D. Water reacts with carbon dioxide to produce carbonic acid, weakening the rock.
This statement accurately describes the process of carbonation rather than hydrolysis. Water and carbon dioxide combine to produce carbonic acid, which then reacts with minerals in rocks, leading to their weakening.
Based on the explanations above, the correct statement is D. Water reacts with carbon dioxide to produce carbonic acid, weakening the rock.
