The Coriolis effect influences the direction of ocean currents. What is the primary cause of the Coriolis effect?

• The rotation of the Earth

• The gravitational pull of the moon

• The temperature difference between the equator and the poles

• The salinity of the ocean water

What percentage of the ocean is made up of density currents?

• 90%

• 50%

• 100%

• 10%

Describe how surface currents help distribute warm water around the globe and moderate Earth's climate.

• Surface currents distribute warm water by moving it from the equator towards the poles, helping to regulate temperatures.

• Surface currents trap warm water in the equator, preventing it from reaching the poles.

• Surface currents have no effect on the distribution of warm water or climate moderation.

• Surface currents distribute warm water by moving it from the poles towards the equator, helping to regulate temperatures.
