Tidal energy is a potential renewable energy resource. Which of the following is the main cause for the formation of tidal waves?
AGravitational pull of the moon
BGravitational pull of the sun
CGravitational pull of both the sun and the moon ✓ Correct
DNone of the above
Correct answer: (C) Gravitational pull of both the sun and the moon — Tidal waves are caused by the gravitational pull of both the sun and the moon, so that is the answer.
Explanation
★Tidal waves are caused by the gravitational pull of both the sun and the moon, so that is the answer.
★Tides rise and fall due to gravity acting on the oceans.
★Both the moon and the sun pull on the sea water.
★So the main cause of tidal waves is the pull of both the sun and the moon.
★The moon alone is not the complete cause.
★So the answer is the gravitational pull of both the sun and the moon.
