Unformatted text preview: GENERAL HOMEWORK #10, GEOLOGY 1020, Spring 2008 1. In general terms, any vertical sequence of sedimentary rocks that exhibits a systematic vertical change in sedimentary facies records what? A. a transgression B. a change through time in depositional environments on the surface of the earth C. a regression 2. A regression is ……. A. evidenced by a vertical facies sequence indicating submergence of the land (e.g., continental deposits overlain by marine deposits) B. can be caused by a shift from barrier island to delta deposition C. a seaward shift in the position of shorelines 3. Which of the following would produce a regression? A. uplifting of the land surface due to faulting B. decreased sediment supply to the shoreline C. an increase in the absolute level of the ocean 4. Which of the following is a possible cause for globally synchronous transgressions and regressions at times scales of 10’s of millions of years? (NOTE: a good follow-up to this on the final would be to ask why!). times scales of 10’s of millions of years?...
