(02.02 MC) When the Earth’s continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation? (3 points)

(01.03 HC) The Helmet Jelly, a type of jellyfish, will migrate from an ocean zone with limited light to the zone that has the most available light. Which zones are the jellyfish moving between and why? (3 points)

(01.02 MC) A deep sea robot is sent to the bottom of the ocean. What will it most likely observe, in terms of the numbers of photosynthetic organisms and light conditions? (3 points)

(01.04 MC) Water is said to have a high boiling point. How does this property of water allow for life in the oceans? (3 points)

(01.02 MC) A submarine robot is operating near the ocean floor. What pressure and temperature data will it most likely record? (3 points)

(03.06 MC) Many species of aquatic snails secrete a slime and are adapted to live in coastal regions. Rather than swim, they move along the ocean floor in shallow water, wedging themselves into crevices or burrowing into sand. What could happen to these snails if they did not have these adaptations? (3 points)

(01.03 MC) The lantern fish is a marine animal that has the unique ability to produce its own light. Why would these organisms most likely be found in deeper ocean zones? (3 points)

(01.03 MC) How can upwelling affect the nutrient and oxygen content of ocean water around coastlines? (3 points)

(01.01 LC) What distinguishes science from other disciplines that do not use scientific methods? (3 points)

(02.05 HC) After studying the historical concentrations of carbon in the oceans for several years, scientists noticed the trend in carbon availability shown in the graph. Based upon this information, they predicted that this pattern would continue. © NOAA PMEL Carbon (Program https://www.pmel.noaa.gov/co2/file/Hawaii+Carbon+Dioxide+Time-Series) Based upon the observed data, what is the most valid conclusion that can be made concerning how ocean carbon levels are changing?
