Detailed explanation-1: -95% of all sedimentary rocks consists of sandstones (made up of sand sized fragments), mudrocks (made up of silt and clay sized fragments), and carbonate rocks (made up of mostly calcite, aragonite, or dolomite). Of these, the mudrocks are most abundant, making up about 65% of all sedimentary rocks.
Detailed explanation-2: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
Detailed explanation-3: -Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.
