The Earth rotating and its tilt of the axis forms the oceans' tides and currents.

Temperature differences in water
Gyresare huge areas found in the middle of the ocean. These are formed when ocean water stays in one place and does not circulate. The force of the Earth's wind patterns create ocean surface currents.
Gyres
There are only two type of Ocean Currents: 1. Surface Currents- 10% of the water in the ocean 2. Deep Water Currents- 90% of the water in the ocean
A surface current is found at the surface of the ocean caused by wind patterns.
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.

The gravitation pull on the earth.

A surface current is a current caused by wind direction
Ocean currents is what forms surface currents. This starts deep in the ocean.
A surface current is found at the surface of the ocean caused by wind patterns.

Surface currents in the ocean are the continuous movements of water found at the surface to just a few feet below, these currents are generated by the planet's prevailing winds-which are a direct result of the Sun's radiation and Earth's rotation.
The energy from the core of the earth causes currents in the molten layers, the way there are currents in the ocean. These currents are what causes the Tectonic Plates to move along the surface of the earth.
