what role do temperature and salinity play in thermohaline circulation?
a. they cause changes in wind direction, which moves denser water in the same direction as the wind, resulting in the deepwater circulation patterns found in the ocean.
b. temperature plays a greater role in thermohaline circulation than salinity does, since it is the temperature of the ocean interacting with the atmosphere that causes deep sea currents.
c. they create and equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
d. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
