Question
Gyres are created due to which of the following? Global wind patterns causing frictional drag on the ocean surface The Coriolis effect Earth's landmasses acting as a barrier for wind-driven ocean currents All of these can effectively create gyres
Solution
All of these can effectively create gyres.
-
Global wind patterns causing frictional drag on the ocean surface: The wind blowing on the surface of the ocean pushes the water, creating a force that starts the water moving in the direction of the wind, thus creating a gyre.
-
The Coriolis effect: This is the deflection of moving objects caused by the rotation of the Earth. In the Northern Hemisphere, the deflection is to the right of the motion; in the Southern Hemisphere, it is to the left. This effect causes the water in the gyres to move in a circular pattern.
