what is a tsunami?
o a wave caused by unusually large tidal forces.
o a sloshing of water back and forth within a lake or a bay.
o a wave that causes wet, clay - rich soils to behave like a liquid during an earthquake.
o a seawave generated by an earthquake, landslide, or submarine volcanic eruption that may destroy coastal cities thousands of kilometers from its source.

Explanation:

A tsunami is a seawave. It is generated by events like earthquakes, landslides, or submarine volcanic eruptions. It can travel thousands of kilometers and destroy coastal cities. Tidal forces (first option) are related to tides, not tsunamis. Sloshing in a lake or bay (second option) is a seiche, not a tsunami. The third option describes liquefaction, not a tsunami.

Answer:

A seawave generated by an earthquake, landslide, or submarine volcanic eruption that may destroy coastal cities thousands of kilometers from its source.
