If you observe a disconformity,you would infer that the region had experienced ________.
A)deposition in shallow water,uplift or lowering of sea level enough to expose the rocks to erosion and non-deposition for a period of time,and subsequent resubmergence of the remaining sedimentary units where they experience new deposition
B)uplift and tilting of sedimentary units that exposes them to erosion over a period of time with subsequent renewed deposition
C)intrusion of igneous rocks into a depositional setting,forcing the sedimentary layers upward and possibly deforming them,followed by subsidence of the remaining sedimentary layers and renewed deposition
D)deposition of sedimentary layers on crystalline igneous or metamorphic rocks that are exposed at the surface of the earth.

Question

Quizplus · Accepted Answer

A disconformity is a type of unconformity where there is a gap in the rock record between parallel sedimentary layers. This gap may result from uplift or lowering of sea level, exposing the rocks to erosion and non-deposition for a period of time, followed by renewed deposition when they are submerged again. This process can create a sequence of sedimentary layers with an erosional surface in between them, indicating a change in depositional environment or a period of non-deposition.
