(02.02 HC) Volcanic eruptions produce lava, which is molten rock that eventually cools into a solid. The gases released during an eruption become trapped in pockets within the lava that remain when the lava solidifies. Scientists can later extract these gases to determine which gases were produced during the eruption, and in what quantities. The table below shows the percent concentration of gases found after the eruption of Mount Saint Helens in Washington, USA. Gases produced during eruption Percent molar concentration H2O 91.58 H2 0.85 CO2 6.64 CO 0.06 SO2 0.2089 H2S 0.3553 S2 0.0039 © 2016 Oregon State EduDo these findings allow the inside-out model to be elevated to a scientific theory? Why or why not? (3 points)

(02.06 LC) Which of the following best defines the carbon cycle? (3 points)

(03.03 LC) The distance from a wave’s equilibrium point to its crest is known as what? (3 points)

(01.01 MC) A scientist wants to test whether the pH, salinity, or temperature of seawater impacts coral development. He sets up an experiment with three conditions: Aquarium 1: Normal pH, normal salinity, normal temperatureAquarium 2: High pH, high salinity, high temperatureAquarium 3: Low pH, low salinity, low temperature What factor would improve experimental design the most? (3 points)

(03.03 MC) A marine biologist is working on a research vessel to study whale calls. His recording devices are measuring depths above 1,000 meters. As his vessel travels to cooler waters and begins to measure at greater depths, the marine biologist needs to make adjustments to his monitoring devices. Why is that? (3 points)

(03.02 MC) A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below. Based on this data, he concludes that the aquarium cannot be considered an isolated system for this experiment. Explain how he came to this conclusion. (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)

(03.05 MC) How would a tsunami most likely affect the abundance of aquatic organisms in the intertidal zone of the ocean? (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 ocean temperature. Their responses are shown in the chart. Student Response Kyle Ocean temperatures will be 22°C in the year 2050. Xavier The salt in oceans causes the temperature to be colder in the summer than in the winter. Rose The ocean temperatures were colder prior to the existence of bony fish. Laurie Ocean temperatures must remain constant in order to go surfing. Which student’s prediction is the most testable using the scientific process? (3 points)
