Ocean Acidification

Ocean acidification begins with 

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

Carbon dioxide and seawater combine to form

• calcium carbonate
• carbon monoxide
• carbonic acid 

The H+ ion is a(n)

• acid
• base
• neutral

Marine organisms make their shells from calcium and

• chloride
• carbonate
• seawater

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

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

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

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

• 10

• 30

• 300

• 1000

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

What was the purpose of breathing into water, adding dry ice to water, and burning candles?

• To produce Carbon dioxide and see what happens to it in water

• To see universal indicator change colors

• To show acid reacting with shells

• To show that the density of dry ice is greater than air
