5 Short Answer 44. How could you tell that a sediment sample had been left on the ocean basin by an iceberg? 45. What might happen to populations of fish or dolphins if the number of plankton in an area of the ocean was reduced? 46. At which time or times of the month would you expect a tidal bore to be highest? 44. ANS: The sediment sample would contain rock and other materials that are normally only found on land. You would have to determine that the materials could not have been washed into the ocean from rivers by turbidity currents but were part of an area that had been covered by a glacier. PTS: 1 DIF: 2 REF: 3 OBJ: ANS: Answers may vary. Sample answer: Since plankton are consumed by small organisms which are in turn food for larger organisms, there would be less food for fish or dolphins in an area where the plankton population was reduced, so the fish and dolphin population would also be reduced. PTS: 1 DIF: 1 REF: 2 OBJ: ANS: at spring tides, during full and new moons
