Answer:

Sediments are generally rocks that have been physically and/or chemically broken down into smaller components, although organic and biological sediments also exist.

Explanation:

When rocks are subjected to physical forces they break down and become smaller pieces of the same type of rock.

When chemical reactions occur, typically due to interactions with H2O, minerals that make up the rock can breakdown. The sediments in this case may be made up of new components not found in the original rock.
