Detailed explanation-1: -Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, mass movement, or glaciers.
Detailed explanation-2: -Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.
Detailed explanation-3: -5.2 Weathering and Erosion. Bedrock refers to the solid rock that makes up the Earth’s outer crust. Weathering is a process that turns bedrock into smaller particles, called sediment.
Detailed explanation-4: -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.
Detailed explanation-5: -The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes.
