Final answer:
Convection currents distribute the Sun's energy in oceans by transferring warm water from the equator to the poles and bringing nutrient-rich water to the surface.
Step-by-step explanation:
Convection currents in the oceans play a crucial role in distributing the Sun's energy around the planet. One way these convection currents work is by transferring warm water from the equator towards the poles. Here, the heat absorbed by the ocean water at the equatorial region, where sunlight is most direct, is moved to the cooler polar regions, moderating the global climate. Another important method is the upwelling of nutrient-rich water to the ocean's surface, which not only supports marine life but also affects the global carbon cycle by bringing nutrients and carbon dioxide-absorbing phytoplankton to the surface. Option B is correct .
