What often caused ocean currents?
A
topography
B
Changes in density
C
earthquakes
D
upwelling
E
wind
Explanation: 

Detailed explanation-1: -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. Currents are cohesive streams of seawater that circulate through the ocean.

Detailed explanation-2: -Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another.

Detailed explanation-3: -But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

Detailed explanation-4: -Ocean Gyre. A gyre is a circular ocean current formed by Earth’s wind patterns and the forces created by the rotation of the planet. Ocean Currents and Climate. Current. 19-May-2022
