Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.

Rocks formed of sediments laid down in successive strata or layers. The materials of which they are formed are derived from preexisting rocks or the skeletal remains of sea creatures.

Rock formed when sediment is compacted and lithified.
