deep currents form when dense water neat the poles sinks and flows slowly along the ocea floor
The movement of wind over the surface of the ocean causes friction. The wind drags the ocean surface with it, making the pattern called surface-ocean wind-drift currents.
Movement of the Tectonic plates below the surface of the earth causes earthquakes. Negative effects of earthquakes are- 1 It causes a great damage to life and property. 2 It sometimes causes Tsunami also.
Currents in the coastal water masses
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.
Solar energy
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.

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.
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
A surface current is a current caused by wind direction

The gravitation pull on the earth.
The Earth rotating and its tilt of the axis forms the oceans' tides and currents.
