If the ice caps continue to melt, then there is less albedo at the poles.  This process will continue to melt more ice and have less albedo.  This is an example of a...

Which natural process removes carbon dioxide from the atmosphere?

• forest fires
• volcanic eruptions
• cellular respiration
• photosynthesis

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

• Water
• Atmosphere
• Sun
• Air
