What two processes allow sediments to turn into rocks?

We learning to form sedimentary rocks in science class. There's always two processes every time sediments turn into rocks. I think one of them is weathering. Can anybody help me?

    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.

    The sediment gets turned into rock by being buried and compacted by pressure from the weight above it. Another way it becomes rock is from being cemented together by material that has been dissolved in water. Often, both cementing and compaction take place together.

    COmpaction and cementation is what turns sediments into rocks.

    Weathering and erosion supply the detritus- sediments- that get compacted and cemented.

    Clastic textile would be shed off of intrusive aspects uncovered on the exterior of topographic highlands and deposited on alluvial followers and in braided fluvial systems in topographic lows, ensuing interior the form of an alluvial hassle-free composed of quartzose detritus. Marine transgression interior the area would bring about deposition of alluvial, marginal and shallow marine or different facies superimposed on the clastic deposits, offering the situations for diagenesis into sandstone. further burial would supply the intense power situations required for great scale dissolution and transport of silica interior the host rock, taking into attention recrystallization into quartzite. it rather is needless to say in basic terms one problem. For an obtrusive occasion, comparable fashions could be postulated for aeolian approaches.
