Which term describes the energy-transporting location around which tide crests rotate in some basins?

• A. Amphidromic Point
• B. Wind Wave
• C. Wavelength
• D. Apogee

Answer: (A)

In tidal basins, the energy of the tidal wave can form a rotating pattern around a point where the tide is essentially zero. This location is called an amphidromic point. The tide crests circulate around this center as the tide cycles, while the amplitude is smallest at the center. The other terms don’t describe this behavior: a wind-driven wave is caused by wind, not by a rotating tidal pattern; wavelength is simply the distance between successive crests, and apogee is a celestial term describing the farthest point in an orbit.
