The model below shows the relationship between greenhouse gases, energy, and global temperature.

When you click on the button titled "With GGas in Atmosphere", you'll see these gases in the atmosphere:

Greenhouse gases =    

Test the model WITH greenhouse gases and WITHOUT greenhouse gases while answering these questions:

• Do SR and IR behave the same way when they collide with a greenhouse gas?
• How do greenhouse gases affect the amount of heat energy beneath the Earth's surface?
