When humans burn fossil fuels, most of the carbon quickly enters the                       as carbon dioxide.

• Water
• Atmosphere
• Sun
• Air

Why is the ocean important to the carbon cycle?

• It keeps sediment containing carbon underwater for millions of years
• The ocean gives out more carbon then it takes in (increases global warming)
• The ocean isn't important to the carbon cycle.
