(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)

(03.06 LC) Outgoing tides can pull organisms out of the intertidal zone and into the open ocean. How does this limit the number of organisms that can live in the intertidal zone? (3 points)

(03.01 MC) Polar bears obtain the majority of their annual nutrient reserves during the late winter. They hunt seals on the surface of sea ice. During this time, the sea ice is also at its highest density. Scientists have been measuring the amount of arctic sea ice for decades, and their results can be seen below. © 2016 Nasa.gov Based on the data trends in the graph, what is the most likely prediction regarding the polar bear? (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)

(02.01 MC) The theory of plate tectonics is supported by evidence that some sediment layers on the floor of the Atlantic Ocean are thinner than expected. How does this observation support the theory of plate tectonics? (3 points)

(02.02 LC) What have scientists determined forms and shapes land masses here on Earth? (3 points)

(02.06 LC) Which of the following best defines the water cycle, also known as the hydrological cycle? (3 points)

(01.03 LC) During which phase of the moon do spring tides typically occur? (3 points)

(02.06 MC) Which process of the hydrological cycle is maintained by the ocean’s large surface area? (3 points)

(02.05 HC) A study was conducted to examine the impact of temperature changes on the number of “non-native species” in an area of the mid-Atlantic ocean. The results of the study are shown in the table below.   Temperature (°C) Number of species Sample 1 15 12 Sample 2 22 10 Sample 3 32 23 Sample 4 27 19   What is the relationship between temperature and non-native species?
