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.
When eroded material mixes with a new rock layer deposited on top of it, this process is referred to as "conglomerate formation" or "sediment mixing." The eroded material, often called sediment or detritus, can become incorporated into the newer layer, leading to a composite of different rock types. This process is common in sedimentary environments where layers of rock are constantly being formed and eroded.
The process of layers of sediment building up is known as sedimentation. Over time, sediments such as sand, silt, and clay accumulate in bodies of water or on land, forming distinct layers. As more layers are deposited, the weight of the upper layers exerts pressure on those beneath, compacting them and causing the minerals within to bind together. This pressure can eventually lead to lithification, transforming loose sediments into solid rock formations.

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.
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.
The surface of igneous rock is broken down over time through erosion processes into smaller particles and eventually sediment, it can be through different erosion processes such as water erosion. Sedimentary rock is formed through layers and layers of sediment being deposited upon each other and the resulting pressure eventually compresses into sedimentary rock over millions of years.

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.
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.
When layers of small sediments stick together because of pressure, compaction occurs. :)

This pressure can eventually lead to lithification, transforming loose sediments into solid rock formations.
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.
