- Reverse Osmosis Desalination
- Bathyal Zone
- Benthic Zone
- a The bottom region of oceans and bodies of fresh water.
- b A popular method for desalinating ocean water. It includes the use of special membranes that allow water under high pressure to pass through and that block the dissolved salts.
- c The mass of mostly microscopic organisms that float or drift freely in the waters of aquatic (freshwater and marine) environments.
- d Begins at the continental slope and extends to a depth of 4,000 meters.
animals that live there: octopi, sea stars, and brachiopods.
- e Potato-shaped lumps of minerals that are found on the abyssal floor of the ocean.
5 Multiple choice questions
- Elements that exist in very small amounts.
ex: gold, zinc, and phosphorus.
- 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
- The shallowest benthic zone that lies between the low-tide and high-tide lines.
- A layer in a body of water in which water temperature drops with increased depth faster than it does in other layers.
- 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
Freezing → The movement of deep, cold, and nutrient-rich water to the surface.
Upwelling → The movement of deep, cold, and nutrient-rich water to the surface.
Pelagic Zone → Extends into the deep waters beyond the continental shelf.
Sublittoral Zone → The shallow benthic zone that most organisms live in; located on the continental shelves and is populated by organisms such as sea stars, brittle stars, and sea lilies.
Sea Salts → The ratio of the mass of a substance to the volume of the substance; commonly expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases.
