Bedrock refers to the solid rock that makes up the Earths outer crust. It is seen in bodies of water, where differences in salinity and differences in temperature create water layers of different densities. The same pattern of sedimentary rock could be expected to form and evidence of the event would reside in the stratified layers. To unlock this lesson you must be a Study.com Member.
