the loss of color in corals that occurs when stressed corals expel the colorful algae that live in them.

• Coral Bleaching

• Pollution

• Eutrophication

• Deoxygenation

a large circular system of ocean currents.

• Gyre

• convection currents

• swells

the process of removing dissolved oxygen from a liquid, such as water.

• deoxygenation

• eutrophication

• photosynthesis

• dead zone

an area of an ocean or large lake where there is not enough oxygen to support marine life.

• Dead Zone

• Coral Bleaching

• Eutrophication

• Pollution

the vertical movement of water toward the ocean’s surface

• Upwelling

• Current

• Rising Tide

Which of the following conclusions can you draw from the data in the graph?

• Humans and natural activities have caused the rise in sea level.

• Direct measurements of sea level show a yearly increase since at least 1993.

  
  

• When the amount of carbon dioxide increases, Earth’s sea level rises.

  
  

• Sea level is not rising; it is actually falling.

  
  

Which correctly describes how the ocean contributes to the oxygen that we breathe?

• Fish produce oxygen through the process of respiration.

  
  

• Phytoplankton produce oxygen through the process of photosynthesis.

  
  

• Corals produce oxygen through the process of mineralization.

  
  

• Phytoplankton produce oxygen through the process of respiration.

  
  

How does this type of walkway benefit groundwater and surface water in a watershed?

• It allows surface water to become runoff.

• It keeps water from soaking into the ground.

  
  

• It prevents groundwater pollution.

  
  

• It allows precipitation to soak into the ground.

  
  

The sum total of all water on Earth and in its atmosphere is called the:

• Biosphere

• Terrasphere

• Hydrosphere

• Liquisphere
