Detailed explanation-1: -Lithification is the process by which sediments combine to form sedimentary rocks. Compaction is a consolidation of sediments due to the intense pressing weight of overlying deposits. With compaction, sediment grains get squished together, reducing the size of the original pore space that divided them.
Detailed explanation-2: -Formation of Sedimentary Rocks Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
Detailed explanation-3: -D) Deposition (sedimentation): particles settled out of transporting agent to form layers of sediment on land or under water. E) Compaction (diagenesis): sediments are buried and compacted due to the weight of overlying sediments accumulating above. Pore waters may be squeezed out.
