Question

water plays an important role in the chenical weatgering of rock in 3-5 drnytrnces identity and explain tepo agents of chemical weathering to su[pport the statement

Answer 1

Water is the main medium and reactant in chemical weathering, enabling reactions that break down minerals and carry dissolved products away. Hydrolysis: water molecules chemically react with silicate minerals (for example feldspar), replacing cations and converting hard minerals into clay and soluble ions, which weakens and disintegrates the rock. Carbonation/dissolution: rainwater absorbs CO2 to form carbonic acid, and this weak acid dissolves carbonate minerals (like calcite in limestone) into soluble bicarbonates, producing features such as cavities and karst landscapes.
