Ocean currents are the movement of water in any direction. It’s kind of like the highways for water and pollutants that effect weather. These currents are found all over the world.
Surface currents are the ones found in the upper 400 metres of ocean (10% of ocean water) most of this kind of current are caused by wind moving across the water creating friction. The friction cause the water to form gyres (a spiral pattern of water. Gravity also has an important role it takes mounts of water near the shore and pulls the water down slopes and that make a current.
Deep water currents are found bellow 400 metres they are called thermohaline circulations these currents are cause also by gravity and density differences in the water.
