Detailed explanation-1: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Detailed explanation-2: -Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth’s surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Detailed explanation-3: -Sedimentary rocks are layered. Some form when particles of rocks and minerals settle out of water or air.
Detailed explanation-4: -Mudstone. Mudstone is made up of fine-grained clay particles (<0.05mm) compressed together. Mudstones form where clay has settled out in calm water-in lakes, lagoons, or deep sea. Flaky mudstone is called shale.
