An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result. which best describes what occurred?

a. continental shifting resulted in a tsunami.
b. continental shifting resulted in a volcano erupting.
c. tidal activity in the subduction zone caused a tsunami.
d. tidal activity in the subduction zone caused a volcano to erupt.

The correct answer is (A)Continental shifting resulted in tsunami.

Continental shift is the movement of tectonic plates. Earthquakes and tsunami are caused as a result of this. A lateral slipping plate movement can result in earthquake because of the pressure and force formed by the collision of plates. Tsunami comes as a result of this continental shift, the effect of movement of tectonic plates can be observed miles away in the form of tsunami.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
