1. Minisubmarines, such as Alvin, are limited in their use because they:cannot descend to very deep watercannot collect samples or take readingstake too long to move along the bottomtake too long to descend and to return to the surface2. The shelf edge is the boundary between the continental shelf and the:shorelinecontinental slopetrenchcontinental rise3. _____ are long, narrow valleys in the ocean floor found near islands or coastal mountain ranges.Ocean basinsMid ocean ridgesTrenchesAbyssal plains4. A _____ is marked by its thick sediment accumulation.continental shelfcontinental slopecontinental risenone of these is correct5. Hudson, Monterey, and Hatteras are examples of:abyssal hillslarge atollsresearch shipssubmarine canyons6. _____ are the flattest places on Earth.Ocean basinsMid ocean ridgesTrenchesAbyssal plains7. An underwater volcano:guyoutatollseamountnone of these8. Abyssal hills are found on the seafloor between:mid-ocean ridges and continental risescontinental rises and deep-sea trenchesdeep-sea trenches and abyssal plainsabyssal plains and mid-ocean ridges9. Atolls are examples of _____.crustal sinkingunderwater volcanoesunderwater mountainsnone of these10. At what point in history did geologists dismiss the premise that the ocean floor was flat?the Fifteenth Centurythe Revolutionary Warthe Civil WarWorld War II11. Which method is currently used LEAST to measure the depth of ocean floors?lead weightsonarsatelliteall of these methods are used currently12. Which method of studying the ocean floor gives some degree of proximity but is efficient in terms of time as well?minisubmarinessonarundersea vehiclesgrab sample13. The ocean floor is divided into two major regions, _____ and _____.continental margins and ocean basinscontinental shelves and ocean basinscontinental slope and ocean basinscontinental slope and continental shelf14. A simple method of obtaining an actual sample of seafloor sediment is with a:lead-weighted linegrab samplerhydraulic-piston corerrobot submarine15. Satellites can obtain information about the seafloor because:the satellite can "see" through sea waterseafloor sediments radiate infrared lightthe color of the surface water varies with seafloor depththe sea surface level varies with seafloor depth16. Deep valleys that run through a continental slope are called:continental risesmid-ocean ridgessubmarine canyonscontinental shelves17. The source of most of the material found on the surface of the abyssal plain is:continental riversocean surfaceabyssal hillsmid-ocean ridges18. Which seafloor feature is not found on active continental margins?deep-sea trenchcontinental risecontinental shelfcontinental slope19.

At the _____, the water depth increases greatly in comparison to areas closer to the shoreline.continental shelfcontinental slopecontinental risenone of these is correct24. Which method of studying the ocean floor allows oceanographers to be closest to the ocean floor?minisubmarinessonarundersea vehiclesgrab sample25. _____ are thought to represent the original sea floor because sediments top them.Ocean basinsMid ocean ridgesTrenchesAbyssal hills26. An underwater volcano with a "sliced top":guyoutatollseamountnone of these27. How does sonar work?an object in space precisely measures the ocean surfacean object emits sound waves that bounce off of the ocean floor and record its deptha line is dropped into the ocean and its length is measured once it hits the floornone of these is correct28. _____ are undersea mountain ranges.Continental risesMid-ocean ridgesSubmarine canyonsContinental shelves29. This area is between the continental slope and ocean basin:continental risesmid-ocean ridgessubmarine canyonscontinental shelves30.

I am sorry, but this should be in your geology book. It is quite a bit to answer
