What is the greenhouse effect?

• the trapping of the sun's warmth in Earth's lower atmosphere
• Argon, Nitrogen, Carbon Dioxide
• The cooling of the Earth
• The heating of the Earth caused by glaciers

What part of the atmosphere is most important in reducing the greenhouse effect?

• Troposphere
• ionosphere
• ozone
• mesosphere

 There is only one gas that causes the greenhouse effect.

• True 
• False

Which of these is NOT a greenhouse gas?

• water vapor
• carbon monoxide
• carbon dioxide
• methane

Carbon Dioxide is one of the Greenhouse Gases in Earth's atmosphere:

• true
• false

Greenhouse gases:

• Occur both naturally and due to human activities.
  

Which of the following is a greenhouse gas?

• oxygen
•  nitrogen
• methane

What happens to most solar radiation when it reaches the surface of the earth?

• it reflects right back into space
• it's collected in solar panels
• it's soaked up by land water and plants
• it disperses throughout the Earth's atmosphere

How can global warming cause sea levels to rise? Choose the best answer.

• by causing it to rain more often
• by melting glaciers and ice caps
• by increasing the number of undersea volcanic eruptions
• by creating bigger and more powerful hurricanes

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide
• trees provide shade which counteracts global warming
• trees absorbs the sun's energy without radiating back into the atmosphere
• trees drain greenhouse gases like methane from soil
