Which mechanism causes the formation of oceanic gyres around subtropical regions?

💡 Explanation

When prevailing winds drive surface waters, Ekman transport occurs because of the Coriolis effect, causing water to be deflected 90 degrees from the wind direction and creating a spiral pattern. Therefore the net effect contributes to the circular motion of oceanic gyres, rather than density gradients, uplift or upwelling.

• Which risk increases when the rate of oceanic plate subduction drastically increases?
• Which global weather pattern is significantly influenced by the Coriolis effect deflection acting on zonal wind circulation?
• What consequence results when rising greenhouse gas levels decrease the temperature gradient between high and low latitudes?
• Which outcome results when subduction of oceanic crust halts?
