Which of the following best describes the relationship between earthquakes and tsunamis? A
An underwater earthquake can cause a tsunami.

B
Both are the result of big volcanic explosions.

C
Tsunami waves are the main cause of earthquakes.

D
Earthquakes prevent tsunamis from occurring.

Tsunamis are usually triggered by earthquakes, volcanic eruptions and underwater explosions, landslides and other mass movements. Underseas earthquakes have generated nearly all the major tsunamis in history. Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.

Explanation:

Answer A is correct because of the fact that tsunamis can be caused by underwater explosions

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
