1. Rotation of the Earth: The rotation of the Earth, also known as the Coriolis effect, influences the direction of ocean currents. In the Northern Hemisphere, currents are deflected to the right, while in the Southern Hemisphere, they are deflected to the left.

2. Air Pressure and wind: Wind-driven currents, which are caused by the wind blowing across the surface of the ocean, are one of the primary types of ocean currents. Changes in air pressure can also affect ocean currents.

3. The density of ocean water: Density-driven currents, also known as thermohaline currents, are caused by differences in the density of ocean water. The density of ocean water is influenced by temperature and salinity.

4. Revolution of the Earth: The revolution of the Earth refers to the Earth's orbit around the Sun, which causes the change of seasons. However, it does not directly influence the ocean currents.

Therefore, the factors that influence the ocean currents are the rotation of the Earth, air pressure and wind, and the density of ocean water.
