The diagram represents solar energy that is absorbed by Earth's land and water surfaces and is changed into heat that radiates back into the atmosphere.What is this process called?

• ozone
• radiation
• greenhouse effect
• evaporation

What happens to the temperature if more greenhouse gases are released into the atmosphere?

• Temperature goes up
• Temperature goes down

Melting of glaciers and polar ice caps....

• will result in cooler temperatures in the Arctic
• will result in sea-levels rising
• Will have no effect on ecosystems
• None of the above

Over the past 200 years, the level of carbon dioxide in the atmosphere has

• decreased slightly.   
• increased until recently, and then decreased.
• increased steadily.   
• stayed about the same.

Without the Greenhouse Effect the Earth would be

• warm

• cold

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

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