Compaction is most significant as a lithification process for sedimentary rocks composed of sand-sized particles. True False

FALSE

Explanation:

Sedimentary rocks are defined as those rocks that are formed due to the combined effect of compaction and cementation process. In order to form sedimentary rocks, at first, the sediments that are transported from other places must be deposited. This deposited sediments over a due course of time, are subjected to high compaction due to the weight of the overlying weight. This results in the transformation of loose sediments into hard rocks. This how sedimentary rocks are formed which are comprised of sand-size particles.  For example, Shale, Sandstone, and Mudstone.

Thus, both the compaction and cementation processes are important for the formation of sedimentary rocks.

Hence, the above-given statement is False.

what are the statements

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
