Sedimentary elements are made up of broken down particles from many different substances. Sedimentary rock forms when multiple particles lump together to make a larger particle until it becomes highly visible and large. For example,
The Mississippi River carries sediment from upstream (typically soil from the dryer parts of the USA) and that sediment gathers into levee's which help protect the coast of Louisiana and the Gulf of Mexico.
Hope this helps and have a nice day.
