Do oceans receive temperature from the Sun the tidal forces the volcanoes or warm currents?

Answer 1

Oceans can receive temperature from the Sun as well as warm ocean currents. Volcanoes can also play a small part in warming the oceans.

The Sun, which we know heats up Earth's area faster at the equator than at the poles, heats up the oceans at the equatorial regions faster than at the poles as well.

Volcanoes, when erupted, can release large amounts of lava that, however, may only heat up the ocean waters for a short period of time.

However, warm ocean currents play the largest role in warming the oceans. These warm currents will bring the warm waters at the equatorial regions up or down to the polar regions, heating up the water at the poles. This is a constant process that is very unlikely to stop.

There is some sort of a chain effect here. In order for the warm ocean currents to bring warm waters up to the polar regions from the equatorial region, there must be some way for warm water to exist. This is because the Sun has been heating up the waters at the equatorial regions, so both the Sun and the warm water currents are equally important in heating up the ocean waters.
