1. Using any resource of your choice, including the websites above, describe the following terms:

Tidal bore:

Tsunami:

Seismic sea wave:

2. Tidal Wave Geometry:

http://en.wikipedia.org/wiki/Tidal_wave

Let the image below represent the Earth’s true tidal wave. It is not representing a wind wave; neither is it representing a tidal bore, a tsunami, a Seiche wave, or a seismic sea wave. This is representing a TRUE tidal wave!

Open the website above and go past all the entertainment entries to the See Also category, and then see the very last entry. Let the crests of the wave below be high tides, and let the troughs be low tides. Use this analogy to answer the questions:

What is the wavelength of Earth’s tidal wave in miles?

What is the wavelength of Earth’s tidal wave in km?
