Science Vocabulary

Which of the following is a benefit of the process of upwelling?

• Warm water is brought to the surface of the ocean to increase its coastal air temperature.

• The wind sweeps warm water toward the ocean's shore to increase erosion.

• Pollutants, such as mercury, are circulated from the ocean's bottom to the surface.

• Large amounts of dissolved nutrients are brought to the ocean's surface.

Which process is diagrammed in the figure below?

• Evaporation

• tidal surge

• continental drift

• upwelling

Which factor best explains why estuaries provide a safe environment for young animals?

• Constant changes in salinity and temperature prevent predators from surviving.

• High pressure, cold temperatures, and lack of light prevent many predators from surviving.

• Pollutants from inflowing rivers provide nutrients that support the development of young animals.

• Estuaries are rich in nutrients and contain roots and grasses that provide shelter for young animals.

Which adaptation would be most important for organisms in the intertidal zone?

• the ability to use bioluminescence

• the ability to withstand high pressure and cold temperatures

• the ability to use chemical nutrients in the water

• the ability to withstand periods underwater and periods exposed to the air

Definition of river basin

• An large 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 of land drained by streams that flow into a bigger river.
  
• The speed at which water flows.
