False
6
Which of the following describes an advantage of a nation wide approach to water protection?
Companies in different states would need to meet only one set of standards.
States would be less involved in deciding the levels of chemicals in water.
Both state and federal agencies would be needed to enforce standards.
Some states would be required to enforce standards lower than their own.
7
Which of these describes the process that allows dissolved oxygen to collect in deepocean water near the sea floor?
Sinking cold water delivers oxygen fromthe surface
Deep sea hydrothermal vents release oxygen
Organic matter on the sea floor releases oxygen as it decays
Deep sea organisms produce oxygen during photosynthesis
8
Which event on west coast of United States provides evidence that upwelling brings nutrient-rich waters to the surface?
a decrease in larval fish populations during upwelling
an increase in algae and phytoplankton during upwelling
a decrease in surface water temperatures during upwelling
an increase in fisheries production during upwelling
9
What would be one practical way to reduce marine dead zones?
Pump oxygen into the water using equipment on fishing vessels.
Harvest marine fish in dead zone areas to reduce oxygen use.
Add bacteria that are able to eat the fast-growing algae.
Prevent fertilizer and other wastes from entering rivers and streams.
10
Mixing of Arctic Ocean water with surface Atlantic currents off the northwestern coast of Europe causes which effect?
sinking of water as it circulates southwest
rapid evaporation and acceleration of currents toward the pole
reversal of current direction backtoward the European coast
rise in water salinity and upwelling of affected currents
11
Which of these events during a storm at sea can add oxygen from the atmosphere to ocean water?
lightning
temperature change

condensation and transpiration
transpiration and precipitation
13
Which statement about the relationship between the ocean and atmosphere is most accurate?
Ocean currents can move faster than air or wind currents
