GPHS SY24 Ocean Acidification/Acids and Bases

Ocean acidification begins with 

• pollution from ships
• carbon dioxide released from combustion
• dumping of waste from cities into the ocean

Marine organisms make their shells from calcium and

• chloride
• carbonate
• seawater

An example of a marine organism that needs calcium carbonate 

• a crab
• a shark
• an octopus

Very slight increases in the acidity of seawater __________  marine organisms that make shells.

• doesn't bother
• has no effect on 
• is unhealthy and stresses

What happens to 1/4 of the greenhouse gases in the atmosphere?

• It is released into space.

• It gets absorbed by the ocean.

According to this slide

• CO₂ is causing marine life to die by "poisoning' the water

• CO₂ is destroying sea shells

• CO₂ is formed from the combustion of Octane

This image demonstrates that

• There is a direct correlation with the atmospheric CO₂ and the CO₂ in seawater

• That pH of the ocean increases as the atmospheric CO₂ increases

• That there is no correlation between pH of the ocean and atmospheric CO₂

As the ocean becomes more acidic, the pH of the water

• increases
• decreases
