Here's why:
* Sediment is the collective term for loose, solid particles that have been transported and deposited by natural forces like water, wind, or ice.
* Rock minerals are the building blocks of rocks and can be broken down into smaller pieces through weathering.
* Plant and animal remains decompose and contribute organic matter to sediment.
Therefore, all these components together form sediment, which is a key ingredient in the formation of sedimentary rocks.
