The correct response is:
A warm water surface current flows along the east coast of the United States and a cold water surface current flows along the west coast of the United States.
This is because the Gulf Stream, a warm ocean current, flows along the eastern coastline, influencing the climate and helping to raise the average temperatures in areas like Cape Hatteras, NC. In contrast, the California Current is a cold ocean current that flows along the western coastline, leading to cooler overall temperatures in regions like Monterey, CA.
