Ocean Currents Review

Ocean currents.

Gulf Stream.

Bodies of water at different temperatures have different densities.

Density differences.

Downwelling is when oxygen-rich water from the surface sinks.

The temperature of the water decreases.

The Coriolis Effect is the deflection of moving objects caused by the rotation of the Earth.

Ocean currents help regulate temperatures and weather patterns by distributing heat around the planet.

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by density differences and occur below the surface.

Gravity helps drive the movement of water, particularly in the formation of deep ocean currents.
