Question
Water masses that drive thermohaline circulation originate near the equator where evaporation is high.
Select one:
True
False
Solution
Assessing the Statement
-
Understanding Thermohaline Circulation: Thermohaline circulation is a large-scale oceanic process driven by differences in temperature (thermo) and salinity (haline). This circulation plays a critical role in global climate by redistributing heat and nutrients across the oceans.
-
Location of Water Mass Origin: The statement claims that water masses that drive thermohaline circulation originate near the equator where evaporation is high. While it is true that high evaporation occurs in equatorial regions, the densest water masses, which significantly drive thermohaline circulation, typically form in polar regions.
-
Conclusion on the Statement: Water that drives thermohaline circulation does not predominantly originate near the equator but rather in cold, salty regions where water becomes denser and sinks.
Final Answer
False. Water masses that drive thermohaline circulation primarily originate in polar regions, not near the equator.
