Heat from Earth's interior and pressure from overlying rock transform the remains of marine sediments into metamorphic rocks, such as slate, marble, or schist. This process, known as metamorphism, causes the minerals in the sediments to recrystallize and reorganize, resulting in a new rock with different properties than the original sediment.
The two primary causes of lithification are compaction, where sediments are squeezed together by the weight of overlying layers, and cementation, where minerals precipitate and bind sediment grains together. These processes transform loose sediment into solid rock.
The process where sediment becomes glued together is called lithification. It involves compaction and cementation of sediment particles to form sedimentary rocks over time. Pressure from overlying layers and the presence of mineral-rich fluids help bind the sediment grains together.
When sediment is deposited in layers and undergoes compaction due to the weight of overlying sediments, it squeezes out water and air, causing the sediment grains to become tightly packed. With time and pressure, this compacted sediment can undergo lithification to become sedimentary rock, such as sandstone or shale.
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.

The reduction of pore space in sediment due to the weight of overlying sediments is known as compaction. Compaction occurs as the pressure from the overlying sediments squeezes out water and air from the pore spaces, causing the sediment grains to become more tightly packed together. This process can lead to the formation of sedimentary rocks 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 partial decomposition of plant remains in an oxygen-poor swamp followed by intense pressure from overlying layers of sediment creates a layer of soft brown material known as peat.

To turn a dead organism into fossil fuel, three main factors are needed: 1) organic material from the dead organism, such as plants or animals, 2) high pressure from layers of sediment accumulating over time, and 3) high temperatures, typically from the Earth's heat and pressure from the overlying sediment. Over millions of years, these conditions transform the organic material into fossil fuels like coal, oil, or natural gas.
A cliff can be turned into a layer of mudstone over millions of years through the process of sedimentation. Sediment, such as mud and silt, can accumulate at the base of the cliff and gradually compact to form mudstone. The weight of the overlying sediment, along with pressure and time, can transform the loose sediment into solid rock.
Compressions form when an organism gets buried by sediment, which puts pressure on the remains and squeezes out any fluids. Over time, the sediment hardens into rock, preserving the flattened impression of the organism. This process helps to create fossils known as compression fossils.
