Explore the website. There is a link for the site on my webpage. At the end of the interactive, complete the fill in the blank activity and when correct, complete it on this handout.

Gases like carbon dioxide and 1).______, in addition to water vapor contribute to the natural 2).______on Earth.

Greenhouse gases in the atmosphere allow short wave radiation from the 3). ______to penetrate and at the same time absorb outgoing heat energy from the 4). ______.

The Earth therefore ends up with a higher average temperature than it would have without the atmosphere.

Burning wood and 5). ______emits 6).______which amplifies the greenhouse effect.

7).______in the atmosphere affect the climate on Earth, but it is really difficult to measure their precise effect.

Greenhouse Effect

8. How do greenhouse gases control Earth’s temperatures?

9-11. In the video, what were the three examples used to describe how humans are adding extra greenhouse gases to the atmosphere?

12-14. What are three examples of fossil fuels?

15. How do extra greenhouse gases affect the amount of heat trapped in Earth’s atmosphere?

16-18. What were the three impacts of increased greenhouse gases mentioned in the video?

Greenhouse Gases

19. What greenhouse gas is over twenty times more powerful at trapping heat when compared to the same amount of CO2?

20. Which greenhouse gas is produced from livestock, landfills, and mining coal?

21. Which greenhouse gas is produced from cutting down and burning vegetation, burning gasoline, and burning coal to produce electricity?

22. Which greenhouse gas is no longer being produced in the U.S.?

23. Which greenhouse gases are better at trapping heat than CO2?

24. How is water vapor (a natural greenhouse gas) affected when Earth warms?

25. What activity in the US produces the most CO2?

All About Carbon

26-32. According to the orange and purple arrows near the end of video, what are areas on Earth that store carbon? What are areas on Earth that release CO2 back into the atmosphere?

Directions for Interactive

Click “Start” to watch how the sunlight travels through the atmosphere to warm the Earth. Next, add one CO2 molecule and one N2 molecule to each interactive. Observe how the CO2 versus the N2 molecule affect the sun’s incoming energy and the Earth’s outgoing energy. Add more of each type of molecule . Observe.

33. Which if any of the molecules are greenhouse gases? What is your evidence?
