GEOLOGY

Detailed explanation-1: -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-2: -Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact, cement, and lithify to form sedimentary rocks.

Detailed explanation-3: -Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.

Detailed explanation-4: -A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure. Rocks are generally made up of two of more minerals, mixed up through geological processes.
