  2. What is the difference between wave height and wavelength? 09.01 • Wave height is the horizontal distance between two successive wave crests; whereas, wavelength is the vertical distance between the crest of a wave and its trough. • Wave height is the vertical distance between the crest of a wave and its trough; whereas, wavelength is the horizontal distance between two successive wave crests. • Wave height is the rate at which a wave travels through the water; whereas, wavelength is the distance over which the wind blows. • Wave height is the time it will take for two successive waves to pass a fixed point; whereas, wavelength is the distance over which the wind blows. • There is essentially no difference; both terms describe the same phenomenon.

  4. Which of the following is an accurate characteristic of a wave moving through shallow water? 09.02 • The wave shape will maintain a circular movement, not an elliptical one. • Waves maintain their energy even though they may travel very long distances. • Wave height increases and the wave crests gather closer together. • There is little to no friction between the sea floor and the wave. • The wave speeds up as it reaches shore.

  6. Waves usually approach shore: 09.03 • Straight on so the wave front is parallel to the shoreline. • Perpendicularly to the shore. • At a slight angle so one part of the wave reaches shore before the rest of it does. • It depends on the elevation. • All of the above

  8. If you are caught in a rip current while swimming at the beach remember to: 09.04 • Swim directly back to the beach underwater as hard as you can directly against the flow. • Swim directly back to the beach above water as hard as you can directly against the flow. • Just lay back and float until you no longer feel the tug of the current. • Doggy paddle in place. • Swim perpendicularly to the shore, across the rip tide, not against it until you no longer feel the tug of the current then swim toward shore.

  10. What must the celestial situation be so that a spring tide may occur? 09.05 • The sun and the moon must be at a 90 degree angle in relation to Earth. • It simply must be during the Spring season. • Spring tides are very rare; they’re usually a consequence of a comet entering Earth’s solar system. • The sun, the moon, and Earth must all be aligned. • Spring tides don’t have anything to do with the sun or the moon; the term is merely another name for extremely high tides that occur as a result of storm surge.
