| Answer» (a) Exfoliation — It is the process of scaling off the curved outer shells of the rock. Exfoliated dome-shaped rocks are largely found in great deserts. (b) Regolith — It is the loose material created by the weathering of rocks i.e. small pieces of rocks. (c) Oxidation — Formation of oxygen compounds with the contact of air with rocks e.g. iron-oxide etc. is known as oxidation. (d) Carbonation — Formation of carbon compounds with the contact of air with rocks e.g. Calcium Carbonate, which is easily carried on by ground water. (e) Desilication — The solution of silica of the rocks with water is called desilication. (f) Humus — It is the decayed vegetation material found in the soil. | |
