5 PROCESSES OF CHEMICAL WEATHERING
Weathering is the breakdown of rocks at the earth's surface, by action of rainwater, extremes of temperature and biological activities. It does not involve the removal of rock materials. Chemical weathering is the weakening and subsequent disintegration of rock by chemical reactions. The following are 5 processes of chemical weathering Hydrolysis this is chemical breakdown of substance when combined with water. Therefore hydrolysis is break down of rock due to reaction between rock and water. The most common example of hydrolysis is feldspar which can be found in granite changing to the clay. When it rains water seep down into the ground and come into contact with granite rock. The feldspar crystals within the granite reacts with the water and are chemically altered to form clay minerals which weaken the rock . Oxidation this is weakening of the rock due to its reaction with oxygen.The oxidation is the process which cause rust. It occur when oxygen in water reacts with ...
