Answer 1

The correct description of the waves formed by tsunamis is:

They cause small waves in the open ocean, but large ones near the shore.

Tsunamis typically have long wavelengths and can travel at high speeds in deep water, causing only small wave heights in the open ocean. However, as they approach the shore and the water depth decreases, the waves can build up and result in large, destructive waves.

Answer 2

are you sure

Answer 3

Yes, I am sure. The behavior of tsunami waves is such that they often remain relatively small in height while traveling across the deep ocean. This is because they have long wavelengths, which can allow them to go unnoticed by ships. However, as they reach shallower coastal waters, the wave height increases significantly due to the energy being compressed into a smaller volume of water, leading to large and potentially destructive waves near the shore.

So, the correct response is indeed:

They cause small waves in the open ocean, but large ones near the shore.
