Oceanography Study Guide Exam 2
OCEANOGRAPHY REVIEW TEST 2
OCE 1001 Chapter 8 (Sections 8.0-8.4) Quiz Questions 1. What are the primary factors that determine wave height? a. Wind speed, length of time wind blows in one direction, and fetch 2. If you have two deep-water waves with periods of 5 and 10 seconds, what can you say about their speeds? (See figure below) b. The longer period wave will have greater speed 3. Where would it be most likely that you would find internal waves in the ocean? c. At the pycnocline 4. What is the difference between longitudinal waves and transverse waves? (Ch. 8, Section “How do waves move?” 5. Describe circular orbital motion. d. The water itself doesn’t travel the whole distance, but the waveform does. As the wave travels, the water passes the energy along by moving in a circle called circular orbital motion. 6. How can you calculate wave speed? e. Wave Speed (S) = Wavelength (L) / Period (T) 7. What are shallow-water waves? f. Waves in which depth (d) is less than 1/20 of the wavelength. (L/20) 8. What are transitional waves? g. Waves that have some characteristics of shallow-water waves and some of deep-water waves 9. Describe how wind-generated waves develop. h. As wind blows over the surface, it creates pressure and stress. Energy imparted by the wind increases the height, length, and speed of the wave. When wave speed equals wind speed, neither wave length or wave height can change. 10. What is constructive interference? i. A form of wave interference in which two waves come together in phase, to produce a greater displacement from the still-water line than that produced by either of the waves alone
OCE 1001 Chapter 8 (Sections 8.5-8.7) Quiz Questions 1. Why do tsunami waves always behave as shallow water waves? a. Their wavelengths are long enough that anywhere in the ocean the water depth is less than L/20 2. What causes
