Question:easy

Which of the following statements is NOT CORRECT in the context of offshore operational environment?

Show Hint

Think about which direction energy actually flows to create ocean surface motion.
Updated On: Jul 28, 2026
  • The motion of ocean's surface can be due to energy transfer from wind to water.
  • Lunar tides are caused by the moon.
  • Solar tides are caused by the sun.
  • The motion of ocean's surface can be due to energy transfer from water to wind.
Show Solution

The Correct Option is D

Solution and Explanation

Step 1: Identify the driving cause of offshore surface motion: In an offshore operational environment, the sea surface is disturbed mainly by two independent sources of energy, wind acting on water, and gravitational pull from the moon and sun acting on the ocean mass.
Step 2: Apply cause and effect logic to option A: Wind is the moving air mass with kinetic energy, and when it blows across open water it pushes and drags the surface layer, so energy naturally flows from the faster moving wind into the slower or stationary water. This is a correct one way cause and effect statement.
Step 3: Apply the same logic to lunar and solar tides: Tides are not caused by wind at all, they arise from gravity. The moon, being closer to earth, produces the dominant tidal bulge, and this is what option B describes correctly. The sun, though far more massive, is far away, so it produces a smaller but still real tidal bulge, which is exactly what option C describes correctly.
Step 4: Test option D against the same cause and effect logic: Option D reverses the flow described in option A, claiming water transfers energy into wind. Physically, water is the much denser, slower responding medium being acted upon, it is not the source pushing energy back into the much lower density air to create wind. Reversing the direction of energy flow like this does not correspond to any accepted description of offshore surface dynamics.
Step 5: Conclude which statement fails: Since three of the four statements, A, B and C, correctly describe recognized offshore phenomena, and only option D inverts a correct relationship into an incorrect one, option D is the statement that is not correct.
Final Answer: $oxed{ ext{(D) The motion of ocean's surface can be due to energy transfer from water to wind}}$
