The correct answer to this open question is the following.
The waters of the earth's ocean help distribute heat from one place to another due to the oceanic currents.
Solar radiation remains in the ocean. The water of the ocean absorbs the sunlight and has a thermal capacity that makes water to be warm. This warm water starts the movement throughout other parts of the planet creating the oceanic currents helped by the rotation of the Earth, the wind, the density of the water and the tides.
