  1. Ocean Life Zones Open Web Exam

  2. 1. When did North America look like this? • Cretaceous • Jurassic • Eocene • Pleistocene

  3. 2. Squid 3. Tubeworms 4. Jellyfish 5. Stingray 6. Manta Ray 7. Lobster (adult) 8. Barnacles (adult) 9. Barnacles (larva) 10. Flyingfish Benthic Nektonic Planktonic Sessile Match the organism with its mode of transportation

  4. 11. What is the main source of food in the bathyal zone? • Plankton • Sunlight • Sulfur compounds from hydrothermal vents • Marine Snow

  5. 12. When did the modern-day Gulf of Mexico first form? • Cretaceous • Jurassic • Eocene • Pleistocene

  6. 13. Hydrothermal vents like these form around… • Ocean trenches • Mid-ocean ridges • Coral Reefs • Littoral Zones

  7. 14-21. Why so much oil in Texas?Place the events in proper order. • Oil migrates up fissures to form reservoirs. • Tropical wet/dry climate + oceanic rifting leads to massive deposits of salt. • Marine snow deposits on floor of gulf. • Pangea begins to split – Florida detaches from Africa, Yucatan from South America, opening up the gulf. • Rockies uplift, leading to massive deposits of silt on top of salt. AB. Dead plankton cooks under pressure to form oil. AC. Under pressure from overlying sediments, salt begins to flow like magma, and form huge diapirs. AD. Rising salt diapirs form fissures in the overlying rock and sediments.

  8. 22. Dive in a Coral Reef 23. Explore a Tide Pool on the beach 24. Man a submersible to a Hydrothermal Vent 25. Swim with a school of tuna. Abyssal Bathyal Littoral Neritic Epipelagic 22-25. What zone are you in, when you…?

  9. 26. How far does light penetrate the ocean? • 10 meters • 100 meters • 200 meters • 500 meters

  10. 27. Which part of the visible spectrum penetrates ocean water the least? • Red • Orange • Yellow • Green • Blue AB. Violet

  11. Yes – THIS is the GULF COAST – REALLY! 28. What state are you in? • Alabama • Tamaulipas • Florida • Quintana Roo • Veracruz

  12. 29. If Riftia pachyptila have no means of eating, how do they survive? • Chemosynthesis from the sulfur produced by the black smokers. • Mutualism with a chemosynthetic bacterium. • Commensalism with a photosynthetic protist. • Parasitism on resident crabs and shrimp.

  13. 30. The Guadalupe Mountains of West Texas and New Mexico are featured in every geology textbook in the world. Why? • They make up the largest rift valley in the world. • They represent an ancient coastline. • Not one but TWO national parks are within their fastnesses. • They represent the largest fossil coral reef in the the world.

  14. The difference between a rich man and a poor man? The price of their toys. 31. Which of James Cameron’s “toys” has gone the deepest? A. AlvinB. MirC. RoverD. Deep-sea Challenger

  15. 32. What zone was the documentary short “The Last Sardine” shot in? • Littoral • Bathypelagic • Coral Reef • Mesopelagic • Epipelagic

  16. The Flower Garden Banks are the northernmost coral reefs in U.S. waters. 33. Mark the factors that make this possible. • Nutrients from the Mississippi River • Deep cold water from the Sigsbee Deep • Salt domes lifting the ocean floor into the photic zone. • All of the above • None of the above

  17. Here are some common baitfish. 34. Which one is more adapted to an epipelagic lifestyle? A. B. C. D.

  18. 35. The growth of what industry has had a direct role in the decline in Kemp’s Ridley Sea Turtles? • Offshore oil drilling • Shrimping • Crabbing • Recreational Scuba Diving
