• The moon
• The Earths rotation
• The Sun
• Fossil Fuels

• The energy that powers most all of our energy
  sources is ---
• the Earths heat.
• the Earths rotation.
• sunlight.

• The picture illustrates the warming of the
  Earths surface by keeping the solar radiation
  from escaping into space. What effect is this?
• Warm blanket effect
• Earth effect
• Energy effect
• Greenhouse effect

5

• What gases are responsible for the greenhouse
  effect?
• Coal, oil and natural gas
• CO2,(Carbon Dioxide), H2O (Water Vapor) AND
  Methane (CH4)
• CO2 only
• Oxygen (O2) and clouds

6

• What are the gases that keep most of the solar
  radiation from escaping into space known as?
• Solar gases
• Global warming
• Greenhouse gases
• Greenhouse effect

7

• The below picture illustrates the burning of
  fossil fuels. What gas is this releasing into
  our atmosphere?
• Carbon Dioxide
• Water vapor
• Methane
• Oxygen

8

• Carbon dioxide is not all bad for the Earth. Who
  needs CO2 to breath?
• Humans
• Cats and dogs
• Plants
• Dolphins

9

• 8. What event would have the worse effect the
  Earths temperature? In other words, what could
  make the Earth get warmer?
• Using solar power instead of burning fossil fuels
• Replanting the forest we have cut down
• Decrease the CO2 emissions from power plants and
  automobiles.
• Increasing the cutting down of forest.

10

• What is responsible for the soaking in of the
  solar energy by the Earths surfaces and clouds?
• Absorption
• Scattering
• Radiation
• Reflection

11

• What is responsible for a portion (a small part)
  of the solar energy being bounced back up?
• Absorption
• Scattering
• Radiation
• Reflection

12

• What makes the sky look blue and the clouds look
  white?
• Absorption
• Scattering
• Radiation
• Reflection

13

  greatly reducing the amount of the suns energy
  from reaching the earth?
• Absorption
• Scattering
• Reflection
• All of them
• None

• It is benefitual because without greenhouse gases
  the Earth would be too cold for life. The
  greenhouse gases form a blanket around Earth
  keeping it nice and warm
• It can be bad because too many greenhouse gases
  may cause the Earth to get warmer and warmer.
