Question

Quizplus · Accepted Answer

As tsunami waves travel towards the shore, their speed decreases due to the shallower depths of coastal waters. However, the energy of the wave must be conserved, so as the speed decreases, the amplitude of the wave increases, causing the wave to grow in height. This is why tsunamis can cause such devastating effects when they reach land.
