How does the Sun play a role in the flow of ocean currents?

• The ocean currents have no relation to the Sun.

• The Sun transfers electrons to the ocean and causes it to flow.

• The Sun’s radiation directly pushes the ocean currents.

• The Sun heats our planet unequally which creates convection currents in the atmosphere that cause ocean currents.
