What is considered to be a true tidal wave? What occurs during these waves? Using the information
you learned in Chapter 10, explain why there needs to be a distinction of a true tidal wave? What will be an ideal response?
ANS:Answer
should include:
? In Chapter 10, you learned that the public and media have altered notions as to what a
tidal wave is. They consider any large wave a "tidal wave." Tsunamis are the most
notable wave to receive this title in the media.
? Tidal bores are true tidal waves because they are generated by the rapid influx of tidal
currents. They form at inlets and river mouths that are exposed to large tidal fluctuations.
? Tidal bores are steep waves that move upstream due to the force of an incoming tidal
crest in an enclosed area,
? These waves move towards land at higher speeds than are theoretically possible for a
given shallow-water wave at that depth. It travels rapidly upriver.
? The danger of tidal bores is reduced because they are predictable. They are associated
with incoming tides.
