(02.05 HC) The two images of the McCall Glacier in Alaska depict how it has changed in size over the past 50 years. © 2016 EPA.gov Predict how the change in this glacier will impact marine ecosystems. (3 points)

(02.01 MC) What aspect of mid-ocean ridges provides the mechanism that allows plate tectonics to occur? (3 points)

(01.01 MC) Students in a high school Marine Science class are learning about the scientific process. Four students were asked to write a testable prediction about deep-sea vents found in the ocean. Their responses are shown in the chart. Student Response Jin Deep-sea vents are too deep. Elizabeth Deep-sea vents are more interesting than caves. Carly Interest in deep-sea vents will decrease in the future. Raymond Ocean surface temperatures are warmer than water at deep-sea vents. Which student’s prediction is the most testable using the scientific process? (3 points)

(01.03 MC) During coastal upwelling, nutrient-rich water rises from the ocean floor to the surface to replace water that has been blown away or moved by currents. How would this most likely change the abiotic components of the ecosystem near the surface where the upwelling is taking place? (3 points)

(01.01 MC) A scientist is investigating the effects of salinity on fish development in the Atlantic Ocean. He places fertilized fish eggs in an aquarium that contains lower salinity than typical Atlantic Ocean water. He observes that the fertilized eggs fail to develop. He concludes that fish eggs do not develop in conditions with low salinity. Why is this an invalid conclusion? (3 points)

(03.03 LC) Which type of wave cannot move without a medium in which to travel? (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)

(01.01 LC) Why is pseudoscience not considered real science? (3 points)

(01.04 MC) Much of life on Earth is based in aquatic biomes. What property of water allows life to survive in liquid water? (3 points)

(02.01 MC) The theory of plate tectonics was developed with the contribution of scientists from many different disciplines. Which of the following is a contribution from geophysicists? (3 points)
