Final answer:
Sedimentary rocks form when sediment settles on the seafloor and is eventually buried, compressed, and cemented together over time.
Step-by-step explanation:
- After entering the sea, sediment settles to the seafloor.
- A river transports sediment into the sea.
- Sediment is buried by continued sedimentation.
- After being buried, grains of sediment are squeezed together by the weight of the sediment above.
- Compacted grains of sediment are cemented together to form sedimentary rock.
