Answer:
B. convection
Explanation:
The sun heats the atmosphere and the surface of the Earth causing convection currents to develop in the atmosphere due to heated air that rise into the atmosphere.The ocean itself regulates temperatures at the lower parts of the atmosphere thus ensures the circulation of water in the ocean through currents and waves.At the equator, heated air loses its density, making it to rise, and when it reaches the troposphere it spreads towards the pole by convection.
