The figure shows the zones of the ocean. Coral reefs require sunlight because reef-building coral contain photosynthetic algae in their tissues. The reefs must sit on the ocean floor for support and must remain underwater to survive. In which ocean zone does a reef most likely thrive?

• oceanic zone

• benthic zone

• neritic zone

• intertidal zone

The diagram shows the process of upwelling along the coast of South America. Westward blowing trade winds blow the warm surface water from the coast to the ocean. Cool nutrient-rich water from below upwells to the surface. Every three to seven years the trade winds weaken, and an El Niño-Southern Oscillation (ENSO) event occurs. Which is the most likely result of an ENSO event?

• decline in the number of cyclones in the Pacific Ocean

• increased number of thunderstorms to the South American mainland

• decline in the fishing industry because of the change in the aquatic food chain

• decline in the number of people scuba diving due to a decrease in the amount of dissolved oxygen

Mary pours 1,000 mL of water into a beaker to represent all of the water on Earth. She then measures out 800 mL and puts it into another beaker. Which portion of Earth’s water is most closely represented by the 800 mL?
