GENERAL GEOLOGY

Detailed explanation-1: -Hydrolysis-the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation-the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.

Detailed explanation-2: -CHEMICAL WEATHERING DUE TO WATER Chemical weathering occurs when water dissolves minerals in rocks, resulting in new compounds. This is also known as hydrolysis.

Detailed explanation-3: -The major reactions involved in chemical weathering are oxidation, hydrolysis, and carbonation. Oxidation is a reaction with oxygen to form an oxide, hydrolysis is reaction with water, and carbonation is a reaction with CO2 to form a carbonate.

Detailed explanation-4: -The most common example of hydrolysis is feldspar, which can be found in granite changing to clay. When it rains, water seeps down into the ground and comes in contact with granite rocks.

Detailed explanation-5: -There are different types of chemical weathering processes, such as solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation.
