what area of the ocean water is controlled by s...

The phrase “what area of the ocean water is controlled by s…” is most likely a shortened version of the question: “What percentage of the ocean’s water is controlled by surface currents?”

The standard answer is:

• About 10% of the ocean’s water is controlled by surface currents.

Quick Scoop

• Surface currents mainly affect the upper 10% of the ocean’s water column.

• These currents are driven largely by wind and the Earth’s rotation , so their influence is strongest near the surface.

• The remaining ~90% of ocean water is influenced more by deep currents driven by density differences (temperature and salinity), not by surface currents.

So if you’re seeing this as a multiple‑choice or forum question, the correct choice is the option closest to 10% of the ocean’s water being controlled by surface currents.
