Bot GPT 4-o mini The four agents of chemical weathering that support the statement about the role of water in the chemical weathering of rock are:
1. **Carbonation which breaks down rocks** - This process involves carbon dioxide dissolving in water to form carbonic acid, which can weather limestone and other rocks.
2. **Dissolution to dissolve and disintegrate rock** - Water can dissolve minerals in rocks, especially soluble ones like halite or gypsum, leading to the breakdown of the rock.
3. **Oxidation where the composition of the rock changes** - Water can facilitate oxidation reactions by interacting with minerals, particularly those containing iron, leading to rusting and alteration of the mineral structure.
4. **Hydrolysis to break down the minerals in the rock** - This process involves water chemically reacting with minerals, especially silicates, to form new minerals and solutes, effectively breaking down the rock.
Options regarding metamorphism and wedging do not directly pertain to chemical weathering caused by water.
