Question

what forms when continents cause ocean currents to deflect to the north and south, forming closed circular current systems?

upwelling

tides

gyres

Explanation:

• Upwelling is the movement of deep, cold water to the surface, not related to closed circular current systems formed by continent - induced deflection.
• Tides are the rise and fall of sea levels due to the gravitational forces of the Moon and Sun, not formed by ocean current deflection around continents.
• Gyres are large - scale, closed circular current systems in the ocean that form when continents deflect ocean currents to the north and south.

Answer:

C. gyres
