(01.03 MC) Downwelling is the process that moves cold, dense water from the ocean surface to the seafloor near the polar regions. How can downwelling affect the ocean water around the poles? (3 points)

(03.01 MC) Over the last few decades, scientists have noticed that lobsters, which obtain heat from the environment rather than generating it themselves, are moving north at a rate of six kilometers per year. What is the best explanation based on these observations? (3 points)

(01.03 MC) In order to simulate mesopelagic zone conditions in a model aquarium design, what temperature and pressure conditions would be required? (3 points)

(01.03 LC) Which ocean zone receives the most of sunlight? (3 points)

(01.03 MC) In which zone do some aquatic organisms rely on bioluminescence to entice prey? (3 points)

(03.03 MC) The diagram below shows two waves. At which letter (A-D) on the diagram is constructive interference going to occur? (3 points) © 2016 Northwestern University Weinberg College of Arts & Sciences

(01.01 MC) A marine scientist observes that fish are found at higher concentrations closer to the coast of California than farther out in the Pacific Ocean. She concludes the fish populations are always large close to the coasts throughout all oceans. Why is this an invalid scientific conclusion? (3 points)

(02.03 LC) How would a hurricane that destroyed large areas of mangrove canopy most greatly impact the biodiversity of the coastal ecosystem? (3 points)

(01.01 MC) A marine scientist is studying photosynthetic organisms, which use sunlight to produce their own food. She observes that they tend to populate shallower ocean depths. She concludes that photosynthetic organisms can only live in areas of low pressure. Why is this an invalid scientific conclusion? (3 points)

(01.02 HC) The graphs below show the change in temperature and salinity of a region of ocean as an instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degrees Celsius, and salinity in parts per thousand. © 2015 protonsforbreakfast.wordpress What is the most valid conclusion based on the data?
