What Describes Sedimentary Rocks?

Explanation:
Sedimentary rocks form from particles deposited on the surface, which become solid through lithification, mainly the process of cementation where minerals precipitate from water and glue the grains together. That binding of sediments is what turns loose material into rock, so cementation of sediments is the best description of how sedimentary rocks come about. In contrast, interlocking crystals are a texture typical of rocks formed by crystallization of molten material or by recrystallization under heat and pressure—characteristic of igneous or metamorphic rocks. High-temperature metamorphism refers to rocks altered by heat and pressure, not the formation of sediments into rock. Solidification of magma describes the cooling and solidification of molten rock to form igneous rocks.
