When layers of small sediments stick together because of pressure, compaction occurs. :)
The process of pressing sediments together to form solid rock is called compaction. It occurs when layers of sediment accumulate on top of each other, with the weight of the overlying layers causing the sediments to be pressed tightly together.
The process by which sediments are glued together to form sedimentary rocks is called lithification. It involves the compaction and cementation of sediments over time, due to the pressure of overlying layers and the precipitation of minerals in the pore spaces of the sediments, binding them together into a solid rock.
Layers in sedimentary rock form from the accumulation of sediments over time. Sediments such as sand, silt, and clay are deposited by wind, water, or ice, and as these sediments settle, they become compacted and cemented together. Each layer represents a different period of deposition, forming a record of Earth's history.
Sediments stick together due to the presence of cementing materials such as minerals like calcite, quartz, or clay. These materials act as a natural glue, binding sediment particles together into cohesive rock formations. Over time, pressure from overlying layers helps to consolidate and solidify the sediments.
This process is known as compaction. As the layers of sediment accumulate, the weight of the overlying sediments compresses the lower layers, squeezing out water and air and causing the grains to come closer together. Over time, through this pressure and the loss of pore space, the sediments solidify into rock.
Layers of sand and other sediments are deposited by the action of wind and water. These layers build deeper over the centuries until the weight of all the top layers results in huge pressure on the lower layers squeezing all the various sediments together into a solid layer of rock.
Igneous rock
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.
compaction or cementation, but im pretty sure it is comoaction.
layers of sediments and dirt that has a lot of heat and pressure
Sediments that are closely packed are typically fine-grained sediments such as clay or silt. These sediments have smaller particle sizes, allowing them to settle closely together and form dense layers. Pressure and time can further compact these sediments into rock formations like shale.
It is called sedimentary rock.
