Quiz 5 - Study Guidelines

Study Outline
The Study Outline should be used as a means for organizing your class notes. Important concepts discussed in class are listed below.

Waves

Know the type of wave energy associated with the ocean

Know the basic characteristics of a simple wave
(such as: crest, trough, wave height, wavelength)

Know the factors that determine how big a wind-generated wave will be. These factors are important in the Sea Region.

Understand the effects of wave interference in the Swell Region.

Know what characteristics of a wave change as it moves from deep water
to shallow water (Surf Region)

Know the definition of tsunamis
(With special focus on those produced by earthquakes)

Tides

Know the definition of tides, tidal period, tidal day

Know the forces, which produce tides (and how they work)

Know the three basic types of tidal patterns that may occur in coastal regions

Know the difference between Spring & Neap tides (and how they are produced)

Know the definition of tidal currents (flood and ebb currents; slack water)

Review Questions
The following questions are designed to help you review the concepts presented in class.
You should refer to both your class notes and the textbook when answering the questions. Also remember to review all assignments and worksheets related to waves and tides!

Waves

1.    Sketch out the characteristics of ideal simple waves.
       Be able to sketch and label the wave crest, trough, wave height,
        wavelength. Include the orbital motion of the water particles.

2.     What is the period of a set of deep-water waves with a wavelength
        of 50 meters and a speed of 10 meters per second?

3. How deep must a submarine dive in order to be below the effects of
the wave described in Question #2?

4.     What is the maximum height that this wave (the wave in Questions 2 &
        3) can reach without breaking?
        (Hint: The critical value for steepness is 1/7)

5.     Suppose a change in the wind speed changes the wavelength of this
        wave from 50 meters to 70 meters. What is the new speed?
        (Remember, the period will not change.)

6.     Describe what could happen in the Swell Region during wave interference.
       Be sure you distinguish between constructive interference and destructive interference.

7.    Some waves make their way landward into shallower waters.
        What things happen to the characteristics of waves as they approach
        a coast and change from deep-water waves to shallow-water waves?

8.     How are tsunamis different from other ocean waves?
        How may tsunamis be produced?

9.    Which type of tsunami is most common and what region of the world
        has these tsunamis on a regular basis?

Tides

1. What forces are responsible for generating the Earth's tides?

2. What are the differences between the 3 basic types of tidal patterns?
Which type of pattern occurs in San Diego?

3. What do the terms "spring tide" and "neap tide" mean?
When do these tides occur?

4.    Describe the differences between flood current, ebb current,
        and slack water. With which part of the tidal cycle are flood
        and ebb currents associated?
