  13. Where does the word nektonic come from and what does it mean?
    greek meaning swimming
  14. Animals that don't swim but scurry, crawl, hop, scoot, burrow or slither a across the bottom of a body of water are called what?
    benthos or benthic animals
  15. Where does the word benthos come from and what does it mean?

  18. Can an animal be benthic and sessile?
    Yes, the sea sponges are sessile and benthic also.
  19. Name an example of a big plankton
    lion's mane jellyfish. tentacles can grow to 100 feet
  20. What are plankton?
    creatures that wander or drift on currents. Most are microscopic. some are actually babies or larva forms of other creatures like lobsters.
  21. What is the greek word that plankton comes from and what does it mean?
    planktos. It means drift or wander.
  22. What are the names of the two kinds of plankton?
    • phytoplankton
    • zooplankton
  23. What do phytoplankton eat?
    Use the sun to make their own food like plants
  24. What do zooplankton eat
  25. Where do zooplankton hang out during the day?
    They hang out in the deep dark water to hide during the day.
  26. Where can you find zooplankton at night?
    They come to the surface to feed on the phytoplankton.
  27. Can zooplankton swim?
    They are very weak swimmers. They have to go where the current takes them but they can swim well enough to swim to the surface at night to eat the phytoplankton.
  28. Where can you find phytoplankton during the day or at night?
    On the top of the water to get the sunlight.
  29. Look at the pictures of zooplankton and phytoplankton and be able to identify them!
  30. What is a plankton bloom?
    When the water gets very warm and plankton multiple so fast the water becomes cloudy with lots of plankton.
  31. Where is there a huge plankton bloom that she showed a picture of in class?
    off the coast of Ireland
  32. Why are plankton so important?
    They are food to many, many marine animals.
  33. What are filter feeders?
    They are animals that clean up the oceans and rivers of the world by eating the microscopic creatures and debris that floats in the water and spew out clean water. Without them in the water, the water would be contaminated!
  34. Name some different filter feeders.
    Giant Clam, small clams, barrel sponges, whale shark, blue whale
  35. Surface currents are caused by what?
    The wind
  36. What are the circular patterns that surface currents form called?
  37. The gyres in the Southern Hemisphere run in what direction?
  38. The gyres in the Northern Hemisphere run in what direction?
  39. Be able to label the gyres on a world map!
  40. What is the end of a river called?
    the mouth
  41. How does the current move water in a river?
    From the head to the mouth
  42. What is the start or beginning of the river called?
    the head
  43. Why are currents important in the ocean
    They move cold water and plankton from the polar regions to the warmer waters and carry warm waters to the polar regions. This helps even the ocean temperatures out. They are like  a huge food delivery system created to feed the animals.
  44. Deep ocean currents are caused by what?
    The water at the top getting heavier and sinking.
  45. Why does the water get heavier and sink?
    1. Cold water always sinks and warm water always rises.


    2. When salt water evaporates it leaves salt behind making the water at the top heavier.
  46. What are thermohaline currents?
    Deep water currents caused by the water at the top getting saltier and heavier due to evaporation and sinking and the cold water sinking.  This forms a thermohaline current.
  47. What does thermo mean?
  48. What does haline mean?
  49. Be able to label and/or draw the Great Ocean Conveyor Belt on a map
  50. What causes the tides?
    The gravitational pull of the moon causes the tides
  51. What is low tide?
    When the water is pulled away from the shore exposing more beach
  52. What is high tide?
    When the water comes way up onto the shore
  53. What is a tide pool?
    It is where water from the high tide gets left behind forming a large puddle of water on the beach during the low tide where sea creatures can get stuck.
  54. How do creatures get out of the tide pool?
    They wait for another high tide to come.
  55. be able to draw and label a diagram of the moon's gravitational pull causing high and low tides.
  56. What are spring tides?
    when the tide is higher than usual and the low tide is lower than usual during a new or full moon.
  57. Name the five oceans and be able to label them on a map
    • Pacific
    • Atlantic
    • Indian
    • Southern
    • Artic
  58. Are oceans fresh or salt water?
    salt water
  59. What are seas?
    They are connected to oceans. They are smaller than oceans but are salt water like oceans. Usually seas are surrounded by land but are attached to an ocean on one side.
  60. Where do rivers and streams flow?
    into oceans or seas.
  61. How does water get into rivers, lakes and streams?
    rain, ice melt from mountain tops, underground springs
  62. Are rivers, lakes, streams fresh or salt water?
  63. What is freshwater?
    water without salt
  64. What is an estuary?
    It is where the river meets with the ocean or sea.
  65. What kind of water is in an estuary?
    brackish water
  66. What is brackish water?
    water that is a mix of fresh water and salt water. The water is less salty and it becomes saltier the closer it is to the ocean.
  67. How does salt get into the seas?
    rivers that flow over rocks containing salt and then the salt flows into the seas/oceans

    volcanoes erupting release salt into the water.
  68. Are seas/oceans getting more or less salty or staying the same?
    They are getting more salty.
  69. What is the continental shelf?
    The part of the continent that is underwater.
  70. What is the continental slope?
    It is the end of the continental shelf where there is a dropoff into the deep ocean. It is like a giant cliff
  71. What is the continental rise?
    One part near the very end of teh continental slope where it reaches the abyssal plain.
  72. What is the abyssal plain?
    It is when you leave the continental slope.
  73. Be able to diagram the continental plain, continental slope and the abyssal plain
  74. Name the ocean zones in order from the continental plain to the abyssal plain.
    sunlit zone---twilight zone---then the midnight zone
  75. Where do most animals live?
    they live in the waters above the continental shelf
  76. Why does the abyssal plain have very few animals?
    food is scarce.
  77. what is bioluminescence?
    where the animals can make their own light through a chemical reaction similar to a firefly
  78. Name animals that are bioluminescent.
    • deep sea anglerfish uses a bioluminescent lure to catch its prey.
    • some plankton are bioluminescent too.
  79. What other animals can you find in the abyssal plain?
    white crabs, jellyfish, gulper eels
  80. What is "whale fall"?
    Where a dead whale falls to the bottom of the ocean floor giving animals enough food to feast for weeks.
  81. Why can you not dive very deep?
    water pressure pushing on you.
  82. How do we explore the deep ocean where we cannot dive ourselves?
    submersibles manned and unmanned
