Question

Tsunamis are potentially destructive waves caused by undersea earthquakes and other disturbances.

A diagram showing how a tsunami is created by an earthquake and the waves approaching the shore.

Eric is using the diagram to help him describe what happens to tsunami waves when they approach the coast. All of the following observations can be made or inferred from the diagram EXCEPT:

A.
their wave base increases.
B.
their wavelength decreases.
C.
their amplitude increases.
D.
their velocity decreases.

Answer 1

A. their wave base increases.

Step-by-step explanation:

The statement "their wave base increases" is not supported by the diagram. In fact, the wave base (the depth at which the water particles are moving in a circular motion) stays relatively constant as the tsunami approaches the shore. Therefore, observation A cannot be made or inferred from the diagram.
