Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. ... Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun.
What are 3 causes of surface currents?
Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. surface create surface currents in the ocean. Different winds cause currents to flow in different directions.
What are the 5 main causes of ocean currents?
Causes of Ocean Currents
- Solar heating. it causes water to expand. ...
- Wind. The Wind is responsible for ocean currents as it blows the water on the surface, causing the currents. ...
- Gravity. Gravity tends to pull items towards the surface of the earth. ...
- The salinity of the water. ...
- Temperature. ...
- Coriolis effect. ...
- Underwater earthquakes.
