Question

how does a tsunami form

Answer 1

Answer:   A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

Explanation:

Answer 2

A tsunami is a wave that spreads in the sea and is caused by an underwater earthquake, a landslide, a volcanic eruption or the fall of a meteorite. ... The higher water descends and vice versa, giving rise to a series of waves that propagate in all directions from the site of the earthquake: the tsunami.
