Which disaster can be generated by a strong earthquake under the sea?
Answer and explanation
Correct answer: Tsunami
The governing concept is seafloor displacement. When a powerful earthquake occurs beneath the sea, the ocean floor may suddenly rise, sink, or shift, displacing a large volume of water. Gravity then spreads this disturbance outward as long tsunami waves. Therefore, option A is correct. Drought results from prolonged lack of rainfall, while fog and hailstorm are atmospheric weather phenomena rather than direct results of undersea tectonic movement.
