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) deposition of sedimentary layers on crystalline igneous or metamorphic rocks that are exposed at the surface of the earth
D) 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

Question

Quizplus · Accepted Answer

A disconformity is a type of unconformity where there is a gap in the rock record between parallel layers of sedimentary rocks. In this case, the rocks have been uplifted or sea levels have lowered enough to expose the rocks to erosion and non-deposition for a period of time, followed by renewed deposition. This process results in a visible boundary or gap between rock layers of different ages.
