Question

The undersea earthquakes can cause ______________.
A. tsunami
B. volcanoes
C. landslide
D. primary rocks

Answer 1

Hint: A submarine, undersea, or underwater earthquake is an earthquake that transpires underwater at the bed of a body of water, particularly an ocean. Understanding plate tectonics helps to clarify the source of submarine earthquakes.

Complete answer: A tsunami is a sequence of waves in a water body instigated by the dislocation of a big bulk of water, usually in an ocean or a huge lake. Earthquakes, volcanic explosions, and other underwater eruptions (including detonations, landslides, glacier calving, meteorite effects, and other turbulences) above or below water all have the possibility of causing a tsunami. Unlike usual ocean waves, which are created by wind, or tides, which are created by the gravitational pull of the Moon and the Sun, a tsunami is caused by the shift of water. Tsunami waves do not look like standard underwater currents or sea waves because their wavelength is far elongated. Rather than seeming like a flouting wave, a tsunami may instead primarily look like a quickly mounting tide. For this reason, it is frequently denoted as a tidal wave, although this practice is not favored by the scientific community as it might give the wrong impression of a causal affiliation between tides and tsunamis.

Thus, option (A) is correct.

Note: Drawbacks can serve as a short-lived cautionary. People who detect drawback (many survivors report an additional sucking sound), can live only if they instantly run for high ground or seek the upper floors of neighboring structures. Also, there are various warnings given out due to weather changes which should be heeded properly.
