If you observe an angular unconformity, 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 submergence 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
D) Uplifting and tilting of sedimentary units that exposes them to erosion over a period of time with subsequent renewed deposition.
