Which is most accurate about tsunamis? Group of answer choices a. They are primarily caused by belching belugas. b. They are big waves caused by changes in the way the Earth rotates from day to day. c. They are waves caused by big tides, such as the tidal bore at the Bay of Fundy in Canada. d. They are big waves caused only by earthquakes. 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.

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.

They can travel as fast as 500 miles per hour.

They cause the ocean to briefly drain away from the shore.
