Step-by-step explanation:
Soil is formed by the method of rock weathering. Weathering is the breaking of rocks into tinier bits as it comes in contact with water, air, or living things. It can happen physically, biologically, or chemically.
Physical weathering: Disintegration of rocks into tiny bits with no modification in their atomic structure. Air and water are factors of physical weathering. When the wind blows on rocks, heavy rain, water waves from the sea can promote a continuous fragmentation of rock bits to debris which ultimately become soil.
Chemical weathering: Chemical reactions in rocks make adjustments in their mineral makeup. Examples of chemical reactions causing weathering are hydrolysis, carbonation, oxidation, and hydration.
Biological weathering: Biological organisms help rock fragmentation. Tree tubers and mosses grow or pierce through rocks and make hole areas that continuously pull rocks apart. Creatures burrow through rocks and form disintegration. Microorganisms discharge chemicals which break down rock minerals.
