Solid rock is broken down into sediment by the processes of weathering. The process of erosion then carries away small bits of rock with wind or water. Once this material is deposited, it can then be transformed into sedimentary rock by the processes of compaction and cementation.
What do you think it is? do you know? Do you even pay attention?
Well the answer would be <span>The process is called "lithification"-- the particles of sediment are pressed together (compaction) and held together by minerals left behind when the water is forced out</span>
