Answer :
The breakdown of rock into sediment process begins the formation of a sedimentary rock.
Detrital rock is a type of sedimentary rock that forms at or near the Earth's surface when sediment builds up and crystallises under normal surface temperatures (chemical rock). Although sedimentary rocks make up the majority of rocks exposed on the surface of the Earth, igneous and metamorphic rocks make up the majority of the crust as a whole.
By weathering preexisting rocks, transporting the weathering byproducts, and depositing them, sedimentary rocks are created. When rocks at the Earth's surface are exposed to the atmosphere (mostly in the form of rainfall) and the hydrosphere, numerous processes of physical disintegration and chemical degradation take place. These activities result in the formation of soil, unconsolidated rock debris, and substances dissolved in runoff and groundwater.
