Question 1
Unconformities that represent a break in the geologic record of deposition are geologically significant ________.
◦ they represent a period of erosion in the region
◦ they give an indication of sea level rise within an ocean basin
◦ they cannot be mapped
◦ the fossils found in the unconformities can be used to correlate global time period
Question 2
If you observe an angular unconformity, you would infer that the region had experienced ________.
◦ uplift and tilting of sedimentary units that exposes them to erosion over a period of time with subsequent renewed deposition
◦ 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
◦ deposition of sedimentary layers on crystalline igneous or metamorphic rocks that are exposed at the surface of the earth
◦ 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
