Answer:
The main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels.
The ocean has absorbed more than 90% of the heat gained by the planet. A new study has found that the ocean has absorbed more than 90 per cent of the heat gained by the planet between 1971 and 2010.
