Answer:
Correct answer is e. "They are big waves caused by very rapid displacement of a lot of water, which may occur in response to an undersea landslide, earthquake, volcanic eruption, or other cause."
Explanation:
Hello!
About 90% of tsunamis are caused by earthquakes that originate beneath the seabed surface. In this case, the intensity of earthquake directly determines the magnitude of tsunami, so not all earthquakes cause tsunamis.
Inside the ocean, the height of the tsunami wave is approximately 1 m, but when it reaches the coast and decreases the depth of water, the height of wave grows steeply.
Tsunamis may have other origins, but all of them have a great destructive power.
