Explain several conditions that will change the shape and force of a tsunami as it contacts the shoreline, and the effect that each condition will potentially have
What will be an ideal response?
ANSWER: A successful answer will include the cause and effect of at least three of the following:
- if the tsunami enters a bay or river mouth, the height of the wave will increase as the opening narrows
- tsunami waves change direction as they pass over shallow water and affect all sides of an island as a result
- as tsunami waves cross into shallow water they will react with the bottom and slow down, creating shorter waves
- shorter wavelengths in shallow water will result in increased wave height?
