what happens to a tsunami when it encounters land?
the tsunami has so much energy that it does not change in character when it encounters land.
the wave height builds rapidly.
the wave quickens.
the wavelength decreases.
the wave slows.

Explanation:

When a tsunami approaches land, the depth of the water decreases. This causes the wave to slow down. As the wave slows, its energy is compressed, leading to a rapid increase in wave height. Also, the wavelength (the distance between successive wave - crests) decreases. A tsunami does change character upon hitting land, and it does not quicken.

Answer:

• The wave height builds rapidly.
• The wavelength decreases.
• The wave slows.
