They're called clastic sedimentary rocks.
Sedimentary rocks form as pieces of loose material get pressed or cemented together. The process of forming sedimentary rocks is lithification.
When older rocks, plants, and other loose material get pressed or cemented together
When pieces of older rocks, plants, and other loose material get pressed or cemented together, they form sedimentary rocks. These rocks are created through processes like compaction and cementation, which help bind the particles together over time.
The name of loose sediment that is held together is called sedimentary rock. These rocks form when loose sediment is compacted and cemented together over time.
Unconsolidated refers to rock or sediment material that has not been lithified, meaning it has not been compacted and cemented together. Unconsolidated materials are loose and can include things like sand, gravel, and clay.
Sedimentary rocks are made by the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
Loose rock sediments are compressed and cemented together over time through processes like lithification, which involve pressure, heat, and chemical reactions. These processes bind the sediment particles together to form solid rocks, such as sandstone or shale, through compaction and cementation.
A sedimentary rock is formed when loose particles, such as sand or clay, are compressed and cemented together over time. This process occurs through the accumulation and lithification of sediments.
A rock made up of angular pebbles cemented together is called a breccia. Breccias are formed through the lithification process, where loose fragments are compacted and consolidated into a coherent rock. These rocks often have a distinctive appearance due to the angular nature of the pebbles within them.
The process of rocks compacting and cementing together to form a solid rock is called lithification. During this process, loose sediment or other rock materials are transformed into sedimentary rocks through pressure and mineral precipitation.
Loose rock material is called detritus.
Sedimentary rocks are formed when loose sediments, such as sand, silt, and clay, are compressed and cemented together over time. The compression helps to squeeze out water and air between the grains, while the cementing material, such as calcite or silica, fills in the spaces between the grains, binding them together to form solid rock.
