wind, gravity, and density
Ocean currents are caused by various factors. They are made from earthquakes, winds, tides and differences in density. The currents of the ocean have an effect on the weather.
The four factors that cause ocean currents: (1) Planet rotation, (2) Wind, (3) Density of the water (depends on temperature and salinity), and (4) Gravitation of the moon and earth. Direction and strength depends on the shape of the shoreline, depth and shape of the bottom, and other currents.
wind
They cause movement of the ocean.
The three factors which control surface currents are the following:Global windsContinental deflection and temperatureThe Coriolis effect
The three factors that form deep ocean currents are temperature, salinity, and density. These factors influence the movement of water masses in the ocean, creating currents that can circulate for thousands of kilometers.
Wind!
It cause Tsunami
Currents in the coastal water masses
The circulation of cold and warm water between the poles and the equator, and the rotation of the earth, cause ocean currents to flow.
The four factors that cause ocean currents: (1) Planet rotation, (2) Wind, (3) Density of the water (depends on temperature and salinity), and (4) Gravitation of the moon. Also the direction and strength depends on the shape of the shoreline, depth and shape of the bottom, and other currents.
