Which phrase provides the best definition of sedimentary rocks? a. rocks that form when a solution evaporates b. rocks that act as glue to hold larger rocks together c. rocks that form from materials that existed in older rocks d. rocks that form from broken pieces of younger rocks

The correct answer is option C. rocks that form from materials that existed in older rocks.

Explanation:

Sedimentary rocks are small pieces of older rocks (such as igneous, metamorphic, and sedimentary) in conjunction with organic remains.

Once they erode, these rocks move across rivers and oceans. While they do, they accumulate sediments that are compressed and heated.

The high temperatures and pressures finally lithify the loose sediment in a sedimentary rock.
