compaction
Cementation
When it is deposited, covered by additional sediments, compressed, and cemented together by minerals.
?
The rock is eroded or weathered away into sediments. The sediments settle and through compaction , the sediments are pushed together to form a sediment. Short Answer: It must be broken down into a sediment.
Compaction does not necessarily cause materials to stick together. Cementation is more like having a binding material between the layers. Even compaction CAN result in binding together of materials such as sandstone.
The process is called cementation.
When it is deposited, covered by additional sediments, compressed, and cemented together by minerals.
The particles in the sediments are cemented as pressure squeezes out water. The dissolved minerals in the water, usually silica or calcite, then become solid (crystallize), tying the particles together.

Cementation is when minerals crystallize and glue the sediments together

The process is called cementation.
The process that presses sediments together is compaction. Thick layers of sediment build up gradually over millions of years. These heavy layers press down on the layers beneath them. The weight of new layers further compacts the sediments, squeezing them tightly together. The layers often remain invisible in sedimentary rock.
In essence, yes. It is made out of sediments which bond together due to chemical reactions
The key to converting sediment into sedimentary rock is often though of as being pressure. And it is only by burial that enough pressure can be generated on a layer of sediment to "press" it into sedimentary rock. With pressure and time comes what is called compaction and the expulsion of (most of) the space between the particles of sediment that were deposited. Let's look at sediments being laid down and turned into sedimentary rock.When sediments are created, moved and deposited, they can consolidate and form a layer or layers. These strata will be composed of particles of organic and inorganic material. Included will be the intersticial spaces between the sediments. Any water present in the pore spaces (and there usually is) will bring with it dissolved minerals. These can precipitate out in the spaces, and will cause cementation, which is the binding of these minerals to the particles of sediment and the "sticking together" of the sediments. Following the deposition of more material, pressure (lithostatic pressure) will build on the underlying strata. The compaction forces the layer to become more dense and to "turn to stone" over time. And sedimentary rock is the result of this process.
