Acid Rain and Ocean Acidification

Ocean acidification begins with 

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

A pH of 3 is how much more acidic than a pH of 6?

• 10

• 30

• 300

What do some marine creatures do with the carbonate ion?

• use it as a food source

• use it as a defense mechanism

• use it to build shells and exoskeletons

• use it to cool body temperatures

Sulfur and nitrogen oxide release into the atmosphere is most responsible for

• ozone depletion
• acid precipitation
• global warming   
• eutrophication
