Thermohaline Density currents

Three factors that influence surface currents are.

• The Coriolis Effect

• location of continents

• density differences

• Air currents (wind)

• temperature of the water

Which is NOT true about salty water?

• Floats on top of freshwater

• Higher density

• It has more molecules than freshwater

• It sinks at the bottom of a container

The Coriolis Effect is caused by

• Earth rotating around the sun

• Earth rotating on its axis

• The tides

• Gravity
