The Coriolis Effect
Thermal energy from the sun is the primary driver for the formation of ocean currents. The sun's heat causes water to expand and rise at the equator, creating warm surface currents. As the water moves towards the poles and cools, it becomes denser and sinks, completing the cycle of ocean circulation.
The Coriolis effect causes surface currents in the Southern Hemisphere to be deflected to the left. This deflection occurs due to the rotation of the Earth, with the Coriolis force being stronger closer to the poles. As a result, ocean currents in the Southern Hemisphere tend to move in a clockwise direction.
Convection causes hot magma to rise towards the surface where it turns and flows parallel to the surface as it hits the crust. As the liquid rock flows beneath the crust it drags the crustal plate along and causes the continents that are on those plates to drift.
As thermal energy is transferred from the core to the mantle, it causes convection currents in the mantle. These currents are responsible for the movement of tectonic plates at the Earth's surface. This movement leads to processes such as seafloor spreading, subduction, and volcanic activity.
The main source of energy for wind currents on Earth is the uneven heating of the Earth's surface by the sun. This causes variations in temperature and pressure, leading to the movement of air masses and the development of wind patterns.
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.

Convection currents in the mantle.
Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.

The gravitation pull on the earth.
Surface currents are created by air currents, earth's rotation, and positions of the continents.
Ocean currents at the SURFACE -- their primary cause is SOLAR ENERGY. Due to solar energy, much of the wind pattern originates and this wind pattern in turn causes ocean currents on the surface.
The sun is major source of energy that power surface currents because the sun causes wind to blow and winds cause surface currents to form
