Chapter 13

  1. What is a marine organism?
    It is an organism that is or lives underwater.
  2. What do lots of oceanographers say the ocean is?
    They say it is one ocean.
  3. How many oceans ocean basins does the earth have?
    It has four main ocean basins.
  4. What are the names of the ocean basins?
    Pacific, Atlantic, Arctic, and Indian.
  5. What is the largest ocean?
    The Pacific.
  6. Does sea level constantly change?
    Yes, it changes all the time forcing oceanographers to use a averaging system that allows them to measure the sea level even though it changes all the time.
  7. What is the local sea level?
    It is the sea level that is more local to an ocean basin such as the Atlantic or the Pacific.
  8. What is a shore?
    It is an area where the ocean and land or lands or island or islands meat up.
  9. What is the continental shelf?
    It is the drop off point of where the rise falls.
  10. What is an abyssal plain?
    It is an area in the ocean bottom, where a valley covers up a drop off point.
  11. What is a continental slope?
    It is the area in which the shore slopes down to the continental shelf.
  12. What is the oceans salinity?
    It is how much salt is in the sea.
  13. Is it possible that the ocean was salty before the flood?
    Yes, it is very likely that the ocean was salty before the flood.
  14. What is brackish water?
    It is water that is less salty but is in the early stages of becoming salt water.
  15. What is with temperature rising and falling in the ocean?
    Hot water is at the top, while cold water is at the bottom.
  16. What is density?
    It determine whether an object will sink or float.
  17. What is the speed of sound?
    It is an object or thing that is going faster than the travel of sound.
  18. What is echolocation?
    It is how animals that cannot see, use to swim and hunt.
  19. What are the different environments of the ocean called?
    Photic Zone, Aphotic Zone, and Abyssal Plane
  20. What are the light conditions in the Aphotic Zone?
    It is completely black due to the lack of sun light bleeding through the ocean.
  21. What is the significance of the carbon cycle?
    It keeps us alive and recycles all the different types of carbon, just like the other cycles do.
  22. What is the Photic Zone?
    Its just like the Littoral Zone, except the salinity and clarity levels are completely different.
  23. What is the Littoral Zone?
    It is an area where the waves crash and everything gets washed up on the sea.
  24. What dot he marine organisms that live in the littoral zone require of?
    A strong body, because they need to be able to survive the violent crashing waves.
  25. What is the Hadal Zone?
    It is like the Abyssal Zone, accept it has a little more light than the Abyssal Zone, it also has more planes.
  26. What is the marine nitrogen cycle?
    It is a cycle in which all marine organisms after they die the nitrogen inside them is recycled.
  27. What would happen if the nitrogen inside marine organisms did not exist?
    Life on earth would soon perish due to nitrogen poisoning.
  28. How do the animals in the Abyssal plane eat?
    They eat the living organic matter that has been falling to the ocean floor from the very top.
  29. How far down is the Abyssal Planes?
    About 20,000 feet.
  30. Why can phytoplankton not survive in the deep ocean areas?
    Because they use the sunlight for their food.
  31. Where is the Photic Zone located?
    Near the surface, about 100-200 m
  32. Where is the Aphotic Zone located?
    About 3,000 4,000 m, or 13,000 ft.
