What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and helping to form sedimentary rocks.

Front

What is cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together, forming solid rock.
