Sediment is made of small particles deposited in water or on land. Over time, compressed under pressure and slowly transformed, sediment forms sedimentary rocks.

The word sediment is also used for material transported by wind or water, and deposited on the surface. Sediments are often eroded again and deposited in a new place. Sometimes they stay, are covered by more sediment. and become rock. The study of how sedimentary rocks are formed is called sedimentology.

In more general use, sediment is any matter which falls to the bottom of a liquid, such as beer.[1]
