Greenhouse Gases and the Greenhouse Effect

T/F: Water vapor is a greenhouse gas

• True
• False

T/F: Some greenhouse gases are naturally present in the Earth's atmosphere

• True
• False

The warming of the atmosphere by the trapping of heat being radiated to space is called

• evaporation
• condensation
• the greenhouse effect
• radiation

Without any greenhouse effect the Earth would be...

• Fine
• Too Cold to Support Life
• Very Hot

The gas molecules that cause the Earth's greenhouse effect are all of the following except

• carbon dioxide

• water vapor

• methane

• nitrous oxide

• oxygen

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

• Temperature goes up
• Temperature goes down

1.  Certain gases in the atmosphere – water vapor, carbon dioxide, methane and nitrous oxide – help maintain the Earth’s temperatures and climate. These are called: __________ . 

• A.  ozone gases
• A.  solar gases
• A.  greenhouse gases 
• A.  stomach gases

What is the atmosphere?

• layer of dirt below the ground

• layer of water at the bottom of the ocean

• layer of air around the Earth

• layer of air inside a greenhouse

"Greenhouse gases trap heat in the atmosphere."

The text describes the effect of greenhouse gases on the Earth. What effect do these gases have on the Earth?

• These gases cool the surface of the Earth and help it stay at a comfortable temperature

• These gases clean the surface of the Earth and lower the amount of pollution on the ground

• These gases freeze the surface of the Earth and help create icebergs in different parts of the ocean

• These gases trap heat, which warms the surface of the Earth and helps it stay at a comfortable, warm average temperature

What happens to the temperature of the atmosphere if there were no greenhouse gases? (Hint: think about Mars)

• The temperature goes up

• The temperature goes down
