Detailed explanation-1: -So, sedimentary rocks are produced from previous rocks that are relentlessly weathered or eroded and then deposited where they undergo compaction and cementation through a process known as lithification-changing of sediments into a rock. This is how the name sedimentary rock was coined.
Detailed explanation-2: -Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
Detailed explanation-3: -Clastic Sedimentary Rocks: If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders.
Detailed explanation-4: -Formation of Sedimentary Rocks Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock.
Detailed explanation-5: -Introduction. 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.
