Question

Consider the following factors:
1. Rotation of the Earth
2. Air pressure and wind
3. Density of ocean water
4. Revolution of the Earth
Which of the above factors influence the ocean currents?

Accepted Answer

The correct answer is B because factors 1, 2, and 3 are primary drivers of ocean currents, while factor 4 is not.

1. Rotation of the Earth: The Earths rotation creates the Coriolis force, which deflects moving water to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, determining the direction of currents.

2. Air pressure and wind: Surface winds are the main driving force for surface ocean currents. Friction between the wind and the water surface pushes the water in the direction the wind blows.

3. Density of ocean water: Differences in temperature and salinity cause variations in water density. Denser water sinks while less dense water rises, creating deep ocean currents known as thermohaline circulation.

4. Revolution of the Earth: The annual movement of the Earth around the Sun influences seasons but does not directly cause or influence the flow of ocean currents.

Therefore, only factors 1, 2, and 3 are correct.
