These small pieces pile up and are cemented together to form new rock is sedimentary rock.
Sedimentary rocks are a class of rock created by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. The mechanisms that lead to these particles settling in one location are collectively known as sedimentation. Sediment is the collective name for the tiny pieces that make up sedimentary rocks. It can be made up of biological or geological waste, such as minerals (organic matter). The formation of the geological debris resulted from the weathering and erosion of pre-existing rocks or from the solidification of molten lava blobs that volcanoes had released. Water, wind, ice, or mass movement, together known as agents of denudation, convey the geological debris to the site of deposition. Body parts and component components of dead aquatic creatures, primarily shells, formed biological debris.
