5 Matching questions

  1. Oceanic Zone
  2. Distillation
  3. Bathyal Zone
  4. Neritic Zone
  5. Desalination
  1. a The area of the pelagic zone above the continental shelves. Has abundant sunlight, moderate temperatures, and relatively low water pressure.
  2. b Extends into the deep waters beyond the continental shelf.
  3. c A process of removing salt from ocean water.
  4. d A method of desalination where ocean water is heated to remove salt. Heat causes liquid water to evaporate and leave dissolved salts behind. When the water vapor condenses, the result is pure fresh water.
  5. e Begins at the continental slope and extends to a depth of 4,000 meters.
    animals that live there: octopi, sea stars, and brachiopods.

  2. The region of an ocean or body of fresh water above the benthic zone.
  3. The raising of aquatic plants and animals for human use or consumption.
  4. Potato-shaped lumps of minerals that are found on the abyssal floor of the ocean.
  5. A measure of the amount of dissolved salts in a given amount of liquid. It can be written as salinity = 35 parts per thousand, or 35%.

5 True/False questions

  1. Pack IceA floating layer of sea ice that completely covers an area of the ocean surface.

          

  2. Abyssal ZoneHas no sunlight because it begins at a depth of 4,000 meters and extends to a depth of 6,000 meters.
    organisms that live there: sponges and worms

          

  3. BenthosOrganisms that live at the bottom of oceans or bodies of fresh water.

          

  4. Sea SaltsA measure of the amount of dissolved salts in a given amount of liquid. It can be written as salinity = 35 parts per thousand, or 35%.
