Compaction is most significant as a lithification process for sedimentary rocks composed of sand-sized particles. a. true b. false

False

Explanation:

Lithification is defined as the summation of compaction and cementation. Finer materials undergo compaction due to the force exerted by the overlying sediment layers. Clay particles (diameter < 0.002mm) undergo more compaction because they are finest in terms of size whereas silt (diameter 0.002-0.06mm) and sand-size sediments (0.06-2mm) are relatively coarser..

So, compaction is relatively a more significant process for clay particles than the silt and sand-sized particles.

Hence the given statement is false.
