According to the density profile shown here, at which depth would you find the coolest, saltiest waters?
Ocean currents have an effect on which two things?
What do we call the constantly moving system of deep-ocean circulation driven by differences in temperature and salinity?

Salt water is _____________ fresh water.
As the temperature of ocean water changes from 10 to 30 degrees C, how does the density change?
What factors create deep ocean currents?

Which of the following drives global thermohaline (conveyor belt) circulation?
What is the upward movement of cold water from the ocean depths called?
As more carbon has been put into the atmosphere, the ocean's pH levels have decreased. This is known as...
What is the most likely cause of the coral bleaching shown below?
Surface ocean temperatures of the eastern tropical Pacific are colder than average during an El Niño event.
An increase in the temperature of seawater is one possible cause of coral bleaching. The Global Coral Bleaching Events graph shows the relationship between the change in seawater temperature and three global coral bleaching events.

The change in seawater temperature is correlated with the amount of carbon dioxide in the atmosphere. The Atmospheric Carbon Dioxide graph shows how the amount of carbon dioxide in he atmosphere has changed since 1960.

Scientists claim that an increase in carbon dioxide in the atmosphere destabilizes coral reef ecosystems. Which evidence from the Global Coral Bleaching Events and Atmospheric Carbon Dioxide graphs supports the claim?
