How does loose sediment become sedimentary rock?
What will be an ideal response?
Answer: As sediment accumulates, older sediment compacts under the weight of overlying younger sediment. Compaction packs sediment grains closer together, facilitating particle clumping because of weak electrical attractions between mineral-grain surfaces. Strong, hard sedimentary rocks form when cementing minerals precipitate in the spaces between sediment grains. Calcite, quartz, clay minerals, and hematite are the most important mineral cements.
