Changes in temperature as water flows from one location to another cause it to expand and contract.
This constant expansion and contraction pushes water in other areas in another direction thus causing it to change temperature and continue the cycle.
Tide shifting also has some effect. The tides (shifting of water from lunar gravity) can often initiate shifts in ocean currents. But it is temperature that has the largest effect on a global scale.
Some would say the wind also has some effect, but most of that is the side effect of the wind changing the temperature of an area as it carrys in a hot or cold front. Wind itself is mostly a side effect of temperature change.
In effect, wind is the side effect of temperature change in the air, much like ocean currents are the side effect of temperature change in water.
Temperature changes as the sun passes over various things cause them to expand or contract, this is the base cause of nearly any shifting or flowing of anything on a global scale such as wind and water.
Any other influence is minimal compared to temperature.

edit note: whoever keeps changing this to just say "wind" has not researched the subject at all.
the seasons
In the unit that they measure ocean currents.
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
they are both currents.
Yes.
deep ocean currents form by the differences in the density of ocean water
Algae have very little to do with ocean currents, other than the fact that they ride it occasionally.
Cold ocean currents sink under warm ocean currents to form deep ocean currents.
Ocean currents is what forms surface currents. This starts deep in the ocean.
advantage of ocean currents
what are the effects of the ocean currents>
Which best explains the relationship between ocean currents and convection currents?(1 point) Responses Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents create a Coriolis effect that increases convection currents. Ocean currents create a Coriolis effect that increases convection currents. Convection currents use the Coriolis effect to generate ocean currents.
yes ocean currents are predictable
In the unit that they measure ocean currents.
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
they are both currents.
They are similar because if you think about it carefully, the ocean currents are caused by the air currents and the air currents are caused by the ocean currents, so, it is all a scientific cycle.
The two causes of ocean currents are wind and the rotation of the earth(etc) The wind blows which makes the currents in the water and the rotation of the earth(gravity) makes currents in the ocean currents. Luaye Sharawy
