Question

Differentiate between physical and chemical weathering process.

Answer 1

When the rocks break down into smaller ones by the force of ice, by the force of wind, by the impact of another rock, by the force of running water, by the friction the process of weathering is then called physical weathering. It is also called mechanical weathering..it only changes the physical properties of the rock.

Chemical weathering occurs at molecular level and involves the exchange of ions between rocks..it changes the composition of rock..chemical properties of rocks are changed..oxidation, hydrolysis and carbonation are main reactions taking place during chemical weathering..chemical properties of the rocks are changed.
