ATSC 113 TEST BANK EXAM QUESTIONS AND
SOLUTIONS GRADED A+
◉ Wind velocity: Answer: Speed of the wind.
◉ Fetch: Answer: Distance over water wind can blow uninterrupted.
◉ Duration: Answer: Amount of time wind blows over water.
◉ If wind speed is slow, waves will always be _________, regardless
of fetch or duration. Answer: Slow
◉ Drag: Answer: Frictional force acting against relative motion of
one fluid with respect to another fluid.
◉ Describe drag between ocean and air. Answer: Texture of the
ocean surface can alter the way wind moves over water, and the drag
produced.
◉ Crest: Answer: Highest point of wave.
◉ Trough: Answer: Lowest point of wave.
, ◉ Wavelength: Answer: Distance from one crest/trough to the next.
◉ Wave height. Answer: Distance from crest to trough, or vice versa.
◉ Wave steepness: Answer: Ratio of wave height to wavelength.
◉ Amplitude: Answer: Distance from centre of wave to crest/trough.
◉ Wave period: Answer: Distance for one wavelength to pass a
certain point.
◉ Confused sea: Answer: Area of large and small waves of different
wavelengths moving in all directions, caused by waves mixing with
pre-existing ones.
◉ Wave train: Answer: Group of waves travelling in same direction.
◉ Faster waves have: Answer: Longer wavelength, shorter wave
period.
◉ Waves in a group are dynamic. Describe how they travel. Answer:
Smaller waves in lead/end, larger waves in middle.
◉ Group velocity: Answer: Speed at which a group of waves travels
across water.
