The following is an example of what type of feedback loop?

• Negative Feedback Loop
• Neutral Feedback Loop
• Positive Feedback Loop
• Global Warming Feedback Loop

In a volcanic eruption, carbon dioxide dissolved in magma is released into the atmosphere during the explosion. What transition is described here?

• Biosphere to geosphere
• Hydrosphere to biosphere
• Geosphere to atmosphere
• Atmosphere to hydrosphere

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...

• fruit loops
• loop di loop
• negative feedback loop
• positive feedback loop

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

Which is an example of anegative feedback loop?

• Decreasing temperature ➜increase in ice cover ➜increase in reflection of sunlight ➜decrease in temperature

• Decreasing temperature ➜decrease in plant cover ➜decrease in absorption of carbon dioxide ➜increase in temperature

What type of feedback is shown by the image?

• open 
• closed
• positive 
• negative

True or False? Many different feedback loops can be occurring at the same time and make it difficult to predict how climate change will affect us.

• True
• False
