- Oceanic Zone
- Bathyal Zone
- Neritic Zone
- a The area of the pelagic zone above the continental shelves. Has abundant sunlight, moderate temperatures, and relatively low water pressure.
- b Extends into the deep waters beyond the continental shelf.
- c A process of removing salt from ocean water.
- 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.
- e Begins at the continental slope and extends to a depth of 4,000 meters.
animals that live there: octopi, sea stars, and brachiopods.

- The raising of aquatic plants and animals for human use or consumption.
- Potato-shaped lumps of minerals that are found on the abyssal floor of the ocean.
- 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
Pack Ice → A floating layer of sea ice that completely covers an area of the ocean surface.
Abyssal Zone → Has 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
Benthos → Organisms that live at the bottom of oceans or bodies of fresh water.
Sea Salts → 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%.
Nekton → The mass of mostly microscopic organisms that float or drift freely in the waters of aquatic (freshwater and marine) environments.
