What is compaction and cementation?
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.
Why is burial usually necessary to turn a sediment into a sedimentary rock?
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.
What is the sequence of events in the lithification of a sandstone?
sand is usually well compacted during deposition, and resists additional compaction during burial. grain-to-grain contact in sand form a supporting framework that helps maintain open spaces between grains.Lithification is a diagenetic process in which loose sediment is converted to hard rocky compaction and cementation.So sediments (sand) are buried the increase in pressure from the weight of the overlaying material pushes the grains closer together. The volume of sediment is reduced and the fluids between the grains are also squeezed out. This leaves the sandstone tightly compressed together this is lithification.
How does a igneous rock become a sedimentary rock?
The igneous rock gets weathered into sediment by wind, water, and ices. The sediment is deposited in a basin and buried. The pressure of burial and the heat inside Earth turns that sediment into stone.
What happens to the rock fragments that get buried after a long time?
It depends how deep it is buried. If it is just covered with more and more sediment, it will compact and cement to become sedimentary rock. If it is buried to the point where it gets into the mantle or a comparable area, it can become melted into an igneous rock or baked and altered into a metamorphic rock.

Is burial of sediment which makes the igneous rocks?
Burial of sediment does not make igneous rock.

What types of rock are metamorphic?
Metamorphic rocks are rocks that can kill you depending on where they are such as the desert ,or mountains.Metamorphic rocks can also create itself and sediments and by sediments going through cementation,compaction,erosion weathering,deposition and burial it eventually becomes a sedimentary rock.
What is geological compaction?
•Loss of porosity during burial •Usually accompanied by a loss of water.
Diagenesis of sedimentary rocks?
Diagenesis - Diagenesis is the process that turns sediment into rock. The first stage of the process is compaction. Compaction occurs as the weight of the overlying material increases. Compaction forces the grains closer together, reducing pore space and eliminating some of the contained water. Some of this water may carry mineral components in solution, and these constituents may later precipitate as new minerals in the pore spaces. This causes cementation, which will then start to bind the individual particles together. Further compaction and burial may cause recrystallization of the minerals to make the rock even harder.Other conditions present during diagenesis, such as the presence of absence of free oxygen may cause other alterations to the original sediment. In an environment where there is excess oxygen (Oxidizing Environment) organic remains will be converted to carbon dioxide and water. Iron will change from Fe2+ to Fe3+, and will change the color of the sediment to a deep red (rust) color. In an environment where there is a depletion of oxygen (Reducing Environment), organic material may be transformed to solid carbon in the form of coal, or may be converted to hydrocarbons, the source of petroleum.

Which processes most likely formed the shale bedrock found near Ithaca New York?
everyone, the answer to this question is burial and compaction
What is Biostratinomy?
preservational/destructional processes occurring between the death of an organism and its final burial in the sediment.
