  • Sedimentary Rock Formation Explained

    Compaction is the compression of the sediments under overlying weight of sediments. Cementation is the process of filling in the gaps in sediments, with minerals that gel them together. Crystal formation may occur here too. With these two processes at work, what was a loose layer of deposits, hardens and solidifies to become rock.
