What are the forces behind the surface currents known as gyre?
In the northern hemisphere, the westerlies are winds that blow water from east to west.
The gyres are made up of currents set in motion by winds and gravity.
Surface currents are deflected at an angle due to the Coriolis effect.
The trade winds start a current that is turned by the Coriolis Effect into a eastward flow along the equator.
Topography determines the location, size, and shape of the gyres.
Thermohaline circulation patterns move surface water from equatorial regions to the poles.

Three forces cause the circulation of a gyre: global wind patterns, Earth's rotation, and Earth's landmasses. Wind drags on the ocean surface, causing water to move in the direction the wind is blowing.

Answer:

The gyres are made up of currents set in motion by winds and gravity

Surface currents are deflected at an angle due to the Coriolis effect.

Topography determines the location, size, and shape of the gyres.

Step-by-step explanation:

The wind direction they have stated is wrong. Thermohaline is deep-sea
