More Co2=less ph

• true

• false

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

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

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

• doesn't bother

• has no effect on 

• is unhealthy and stresses

Which molecule makes water acidic?

• Carbonate Ions

• Carbon Dioxide

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
