Exam 9: Tides

A lunar day is shorter than a solar day.

The energy of tidal currents can be harnessed to drive turbines and generate electricity.

The difference between centripetal forces and gravitational forces is called the:

The tide-generating force is inversely proportional to the cube of the distance.

A tidal current can produce a rapidly spinning body of water called a vortex or:

-Compare diurnal, semidiurnal, and mixed tidal patterns.

The seaward flow of water through an inlet (such as a bay or river)due to tidal forces is called an ebb current.

When spring tides coincide with lunar perigee, the tidal range is increased.
