Question

Tsunami waves become bigger when they approach the coast (true or false)
true​

Answer 1

Answer:

Like a “normal” wave, the energy of a tsunami becomes more and more concentrated as the tsunami approaches the shoreline. Its crests grow higher and higher as the water becomes shallower and shallower. Not all earthquakes in the ocean cause tsunami.

True

• As a tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms. Because of this shoaling effect, a tsunami, imperceptible at sea, may grow to be several meters or more in height near the coast.
