Waves

The lowest point on a wave is the

• crest

• wavelength

• trough

• benthic

The time it takes identical points on two waves to pass through the same point is referred to as its

Wavelength is best described as the

• Vertical distance between a wave’s crest and the next trough

• Horizontal distance, either between the crests or troughs of two

  consecutive waves.

• The number of waves that pass a given point in a designated amount of time

• The distance a wave travels in one second

If you followed a single drop of water during a passing wave, it would:

• Move horizontally

• Remain stationary

• Move away from shore

• Move in a circle

Deep water waves are defined as waves found in water deeper than:

• 1/2 their wavelength

• 1/3 their wavelength

Shallow water waves are defined as waves in water shallower than:

Which of the following is true of a tsunami?

• A tsunami is a deep water wave

• A tsunami may be caused by the tides, and thus is sometimes accurately

  called a tidal wave

• The speed of a tsunami can be calculated by dividing its depth(d) by the

  acceleration due to gravity (g)

• A tsunami is caused by displacement of large volumes of water, for

  example during an earthquake
