Which is NOT a factor that affects ocean currents?

Correct option is A

Correct Answer: (a) Soil type
Explanation:
· Ocean currents are influenced by wind patterns (surface currents driven by prevailing winds), temperature and salinity differences (thermohaline circulation), and the Earth’s rotation (Coriolis force) which deflects currents.
· Soil type on land does not directly affect large-scale ocean currents, so it is not a factor.
Information Booster:
· Warm currents tend to raise sea surface temperature and increase rainfall on adjacent coasts; cold currents often reduce coastal rainfall and can lead to arid conditions.
Additional Knowledge:
· Local coastal topography, tides and continental configuration also modulate ocean current patterns.
