Answer 2

Tsunami is a large wave usually caused by an undersea earthquake.

Explanation

Tsunamis are big waves caused by earthquakes or volcanic eruptions beneath the ocean. go in the depths of the ocean, moving ridge waves don't dramatically increase tall.

However because the waves travel inland, they build up to higher and higher heights because the depth of the ocean decreases.
The speed of moving ridge waves depends on ocean depth instead of the space from the supply of the wave. moving ridge waves might travel as quick as jet planes over deep waters, solely deceleration down once reaching shallow water.
