Sedimentary rocks form from which process?

Explanation:
Sedimentary rocks form when loose sediments are compacted and cemented together. This process, lithification, happens in two main steps: compaction, where the weight of overlying layers squeezes the grains tighter, and cementation, where minerals dissolved in water crystallize between the grains and glue them together. Over time, sediments like sand, mud, or fragments of shells become a solid rock as these steps lock the particles in place. Other rock types form by different processes—metamorphic rocks are altered by heat and pressure, and igneous rocks come from the cooling of molten material.
