Clay minerals can cement layers of sediment together to form shale, a type of sedimentary rock characterized by its fine-grained nature and distinct layering.
Sediment becomes compacted through the pressure of overlying layers of sediment, water, and other materials. The weight from these layers squeezes the sediment particles together, forcing out the spaces between them. Over time, this compaction can lead to the formation of sedimentary rock.
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
Sedimentary rocks are formed through the deposition and solidification of sediment that has been eroded, transported, and often compacted, creating layers of rock over time. They can contain fossils and provide valuable information about Earth's history and past environments. Examples include sandstone, limestone, and shale.
Rivers, streams, glaciers, and wind are four agents responsible for depositing sediment in the water. These agents transport eroded material and deposit it in bodies of water, contributing to the formation of sediment layers.

Overburden pressure.
The process is called sedimentation. It occurs when eroded particles are carried by water or wind and deposited in a new location, forming layers of sediment over time.

Igneous rock is weathered and eroded into smaller pieces. These pieces are then transported and deposited, creating layers of sediment. Over time, the weight of additional sediment layers compresses the lower layers, forcing them to lithify into sedimentary rock through processes like compaction and cementation.

After weathering, sediment is transported by wind, water, or ice to a new location where it can accumulate and create sedimentary rock through the process of lithification. Sediment may also be eroded further or eventually buried, compacted, and cemented to form sedimentary layers.
The lowest layer of sediment is called bedrock. Bedrock is the solid rock that lies beneath soil and sediment layers and serves as the foundation for the Earth's crust. It is typically composed of igneous, metamorphic, or sedimentary rock that has not been significantly weathered or eroded.
When layers of small sediments stick together because of pressure, compaction occurs. :)

Rivers, streams, glaciers, and wind are four agents responsible for depositing sediment in the water. These agents transport eroded material and deposit it in bodies of water, contributing to the formation of sediment layers.
The process is called lithification. It involves the compaction and cementation of loose sediment to form sedimentary rock. Pressure from overlying layers squeezes out water and air, causing the sediment grains to pack together more tightly and creating solid rock.
