Exam 8: Waves and Water Dynamics

Refer to the figure below detailing wave characteristics. Use the information on the figure to answer the following question. -The wavelength is labeled with the number:

A curling wave formed over an air pocket is called a plunging breaker.

The height of a wave depends upon:

Tsunamis can be generated by geological activity that causes a sudden change in sea floor elevation such as submarine fault motion.

Deep-water waves move faster than shallow water waves because they are not slowed by friction with the ocean bottom.

Rogue waves are generated by destructive interference patterns of ocean swells.

If a surfer wishes to have a really long ride, what type of wave should he or she look for?

Briefly describe how tsunami are generated and include a description of characteristics such as wavelength and wave speed. Do tsunami behave as shallow-water waves? Why or why not and how does this influence their movement in shallow versus deeper water? What would the shoreline look like when the trough of tsunami arrives?

The orbital motion of water molecules in a wave goes down to a depth equal to the wavelength divided by two.

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -disturbing force

The diameter of a wave orbital at the surface is equal to:

Wave speed is equal to:

A storm surge might form in association with a seafloor avalanche.

Refer to the figure below detailing wave characteristics. Use the information on the figure to answer the following question. -The crest is the portion of the wave corresponding to the number:

Match the term or person with the appropriate phrase. You may use each answer once, more than once or not at all. -ratio of wave height to wavelength at which waves break

Waves that are breaking along the shore and are forming a curling crest over an air pocket are called:

Refer to the figure below detailing wave characteristics. Use the information on the figure to answer the following question. -The trough of the wave corresponds to the number:

The horizontal distance between two successive troughs is called the wave height.

Constructive interference results in larger waves whereas destructive interference produces:

The first wave that forms when the wind begins to blow across the ocean surface is a:
