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.

the answer is   c.) 1575 j.

explanation:

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
