Answer:
Correct answer is option C
Step-by-step explanation:
Tsunami is derived from the Japanese words “tsu,” meaning harbor, and “nami,” meaning wave.
A tsunami is not a single wave but a series of waves generated by geological changes near or below the ocean floor. A tsunami can be produced by an event at the sea, like an earthquake, landslide, volcanic eruption, meteor strike, etc.
Properties of Tsunami Waves:
1) Tsunami waves are a series of waves of very long wavelengths and period created in the ocean due to impulsive disarray.
2) Tsunamis behave as shallow water waves because of their long wavelength. Their period ranges from 10 minutes to two hours, and their wavelength exceeds 500 km.
3) The rate of energy loss in a tsunami is very low due to its very large wavelength.
4) They travel at high speed in deep water and cover a great distance.
Damage caused by the tsunami:
1) Death
2) Property loss
3) Physiographical changes
4) Motion of the earth
5) Decline in soil fertility
6) Effect on Marine
