Eventually, the weight of the sediments will compress the sediments at the

 bottom, squashing out the water and cementing the pieces of rock together.

 

This process could occur over millions of years. Sedimentary rocks often

contain fossils due to the amount of time it take smaking them – this could be

skeletons of small animalsplants or shells.

 

The grain of sedimentary rock is mostly rounded – this is due to erosion of

sharp edges over time.

 

Examples of sedimentary rock include:

chalk, limestone, sandstone and gypsum.
