Petroleum Reservoirs and Sedimentation Processes Quiz

A gap in the rock record where layers are missing due to erosion before new sediment is deposited

Disconformities are formed by erosional processes that remove existing rock layers before new sediment is deposited.

The uplift of rock beds above sea level is caused by tectonic forces.
