Consider the following factors:
- Rotation of the Earth
- Air pressure and wind
- The density of ocean water
- Revolution of the Earth
Which of the above factors influence the ocean currents?
Detailed Explanation:
✅ Statement 1 – Correct: Rotation of the Earth causes the Coriolis effect, which deflects ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
✅ Statement 2 – Correct: Air pressure and wind generate wind-driven currents by exerting friction on the ocean surface; prevailing winds like Trade Winds and Westerlies drive major surface currents.
✅ Statement 3 – Correct: Density of ocean water, determined by temperature and salinity, drives thermohaline circulation (deep ocean currents).
❌ Statement 4 – Incorrect: Revolution of the Earth (orbit around the Sun) causes seasonal changes but does not directly influence ocean currents.
