Describe the two processes by which sediments are transformed into sedimentary rocks. which is the more effective process in the lithification of sand- and gravel-sized sediments?

Respuesta :

Answer:

1. Compaction occurs where pressure is placed on loosely packed sediment. The volume of the sediment is reduced and water is squeezed out.

2. Cementation occurs when mineral-bearing water circulates among the grains, hardens, and cements the sediment grains together. This process is most effective when lithifying sand and gravel-sized sediments.
