List and discuss the processes of soil formation

the processes of soil formation are:
-Physical process
-Chemical process
-Biological process

PHYSICAL PROCESS
Temperature: as a result of the expansion and contraction of as they are heated, rocks breaks into tiny pieces.
Water: the action of running water which carries rock particles makes them to rub against one another causing them to break.
Ice: water which freezes up within crevices of rock eventually melts resulting in the pebbles which heat other rocks to break them into tiny pieces.
Wind: when the wind is blowing, it carries some rock pebbles which hit other rocks to break them into tiny pieces.
CHEMICAL PROCESS:
Solution: this is when soluble rock dissolves completely in water resulting in the breaking of rocks into tiny pieces.
Carbonation: carbonation dissolves in water to form weak acid which can dissolve or break some rock.
Oxidation: this is the reaction of oxygen with certain rock minerals which result in breaking down the rock into tiny pieces.
Hydration: this is the attachment of water with rock minerals which result in alteration of the minerals.
Hydrolysis: this is the reaction of water with rock minerals to produce a rock entirely different from the original one.
BIOLOGICAL PROCESS:
The action of animals e.g earthworms, termites causes the rocks to break. Movement of some animals also helps to breakdown rock.
The roots of plants penetrate rocks resulting in the breakage.
The activities of man in the process of farm operations e.g use of harrow, plough, etc. help to break the rocks into tiny particles.
