the area of the shore and seabed that is exposed to the air at low tide and submerged at high tide, i.e. the area between tide marks

• neritic zone

• intertidal zone

• photic zone

• upwelling

A ship is mapping the structure of the ocean floor using sonar technology. Which describes the basic method used in this type of mapping?

• A radio wave is sent from the ship and reflects off the ocean floor back to a receiver on the ship.

• A sound wave is sent from the ship and reflects off the ocean floor back to a receiver on the ship.

• A radio wave is sent by the ship and is absorbed by the ocean floor.

• A sound wave is sent by the ship and is absorbed by the ocean floor.

Deep ocean bottoms are generally cold, dark, and lifeless. However, some organisms have been discovered existing near thermal vents on the ocean floor. What makes these organisms different from MOST other organisms in the way that they obtain energy?

• They do not use oxygen.

• They can live near hot water.

• They can tolerate high pressure.

• They do not use sunlight.

Definition of estuary

• Wide variety of plants and animals live in an estuary.

• An area of land drained by a river and its branches (streams and creeks).
  

• a process in which deep, cold water rises toward the surface

• an area where a river flows into the ocean (fresh and salt water mix)

Definition of salinity

• The measure of how salty water is

• The speed at which water flows.

• Water that is slightly salty.
  

• a process in which deep, cold water rises toward the surface
  

Why is upwelling an important process in a marine ecosystem?

• Upwelling replaces sand and gravel on beaches lost as the result of wave and tidal action.

• Upwelling decreases the temperature differences between different layers of ocean water.

• Upwelling cycles nutrients from decomposers along the ocean floor to producers in surface waters.

• Upwelling returns salt to the surface from the benthic zone as part of the global conveyor belt current.
