When there is a single high tide and a single lov.r tide each tidal day the pattern is described as: {a} mixed {b} diurnal {c} semidittrnal 2. Because of the Coriolis effect surface ocean currents are deflected to the of their path of motion in the Northern Hemisphere. Mm {h} left 3. An equatorward-moving ocean current is: {a} warm b] cold {e} warm in the Northern Hemisphere and cold in the Soul crrt Hemisphere [d] cold in the Northern Hemisphere and warm in the Southern Hemisphere a. The Gulf Stream was first discovered about the time of the Revolutionary War. (a) True [b] False 5. The energy that drivee surface ocean currents such as the Gulf Stream comes from: {a} salinity variations {b} Coriolis force [cl prevailing winds {d} density differences to} wave activityI d. The world's first tidal power station to produce electricity was built in: ta] the United States (b) Canada to! France [d]: Norway to} The Soviet Union I The world's first tidal power station to produce electricity was built in: {a} the United States {b} Canada {c} France (d) Norway [e]: The Soviet Union {a} has been gradually rising ldl fell 3. Over the past 100 years sea level: {b} has remained unchanged {c} has bcen gra ually falling sharply for about it! years and then gradually began to rise 9. Fetch is: {a} a method of shoreline erosion control {bl the distance between the trough of a wave and the still water level {c} the circular pattern made by water particles when a wave passes {d} a type of wave-cut platform (e) none of the above III}. The predicted global change in air temperamms over the next lilil years will probably be linked to increasing amounts of carbon dioxide in the atmosphere. (a; True {is} False II. .P. fiat benchlilte surface cut in reel: is a: {a} sea stack {b} jetty {c} tomb-ole {d} spit gel wave-cut platform [2. Deep ocean circulation is driven largely by; (a) tidal forces exerted by the sun and moon {b} the wind to} large schools of fish swimming in a big circle td} variations in water temperature and salinity {e} the coriolis force 13. The rising of cold 1crater from deeper layers to replace warmer surface water is called . {a} flood tide {b} replenishment {c} cold currents id! upwelling [e] eddy l4. Barrier islands are more common along the Pacific Coast of the United States than along the Gulf of Mexico ICoast. {a} True Eb} False 15. 1'r‘r"hit:h one of the following neonatal regions is dominated by a cold ocean current? [a] Pacific Coast {b} Atlantic Coast to) Gulf of Mexico 115. One result of waste refraction is that: in! wave energy is concentrated on headlands projecting into the water {bl wave energy is concentrated in the recessed areas between headlands to] wave energy is largely dissipated before the waves reach the shore {d} headlands are enlarged because sediment is deposited on their seaward side ll. 1ll'r'hich. one of the following is associated with a first quarter moon? {a} spring tide [b] ebb tide fol flood tide Ed} neap tide 13— The horizontal flow of water accompanying the rise and fall of the ride. {a} neap current {b} spring tide (of: flood tide {d} tidal __ current [9. The Texas Gulf Coast: (a) is associated with a subduction plate lb} maintains its present form by erosion of the coast to} is a former river delta that was flooded by a rise in sea level {d} is bordered by a fringing coral reef to} has been created by deposition of sand 20. Earth's tides are influenced more by the sun because it is much more massive than the moon. {a} True lb] False 21. The movement of water within the surf zone that parallels the shore is termed.- ta]: tidal current {b} salinity currenl (cl beach drift {d} longshore current is} rip current —I|I-.-. 22. Tidal flats are exposed during ebb tide. ta! True fb} False 23. Which of the following water masses would be the most dense? {a} warm water with a high salinity {h} cold water with a high salinity {e} cold water with a low salinity {d} warm water with a low salinity {c} all of these would be equally done: 14. The Coriolis effect: [a] applies only to tides {ht is gassed by the earth's rotation to] exists only in the Northern Hemisphere {d} is greatest near the equator {c} Causes all of the ocean's currents to conform exactly to the prevailing wind patterns 25. The first and perhaps most comprehensive study of the global ocean lasted from December “in until May rats and is known as the expedition. fa! IChallenger {h} Fram {c} Meteor {d} Alvin {e} Maury 26. Which one of the following is not a resource extracted from sea- water? {a} bromine {b} common salt {sodium chloride} [c] gold {d} magnesium '— 21 Which ocean has the greatest average depth? [a] Atlantic {b} Pacific {c} Indian (d) Arctic 23. The Dcean is saltiest. {a} Atlantic {b} Pacific {c} Indian {d} Arctic tel Mediterranean 29. The development of this instrument greatly enhanced our knowledge of the ocean floor. {a} pulsar {bi echo sounder [c] submarine transit (d) tuzon‘teter t'e} infrared opscanner SD. in regions of heavy precipitation the salinity of surface waters is reduced. fa] True [b] False 31. The surface waters in regions where evaporation rates are high such as the Red Sea have higher than average salinities. [a]: True {b} False 43. Name the instrument used to measure water depths in the ocean by employing sound waves. (all radar {b} depth guage {c} radio reflection {d} sonar 44. Corals living near sea level have a different characteristic than corals living at 151') foot depth. What factor explains this vertical zonation of coral types? {a} salinity {b} available light [cl water circulation (d) temperature 45. The ocean floors are dotted with isolated volcanic peaks called {a} mid‘ocean ridges (b) continental rises to} upwarps t; } seamounts "F" 46. 1'i'ifhich of the following is NOT true of deep ocean trenches? [a] they are long and narrow depressions in the ocean floor lb] they are sites where plates plunge back into the mantle {c} thgy are geologically very stable {d} they may act as sediment traps 4'1. Oceanic ridges ettist only in the Atlantic and Pacific. {a} True {b} False 413.
