A student researching ocean currents has taken notes:
• Ocean currents distribute heat around the globe • The Gulf Stream warms northern Europe's climate • Currents are driven by wind, temperature, and salinity differences • Changes in currents can affect weather patterns worldwide • Marine life migrates along current pathways
The student wants to explain currents' role in regulating climate.
Ocean currents are driven by wind, temperature differences, and salinity.
Ocean currents regulate climate by distributing heat globally—the Gulf Stream, for example, keeps northern Europe warmer than its latitude would suggest.
Marine life follows and migrates along ocean current pathways.
Changes in ocean currents can significantly affect weather patterns worldwide.
Correct Answer: B
Choice B. Heat distribution and Gulf Stream warming Europe explain climate regulation.
