  1. 2. Fill in the blank: When the Earth __________ more energy, the temperature increases
  2. 7. A period in Earth's history where the temperature was very cold. Most of the Earth was covered in frozen water. During this time, there is LESS energy in the Earth system
  3. 9. When the amount of this gas increases in the atmosphere, the amount of energy absorbed by Earth also increases. This gas comes from combustion.
  4. 11. Over the last 100 years, the Earth's temperature has done this
  5. 12. When the amount of this gas increases in the atmosphere, the amount of energy absorbed by Earth also increases. This gas comes from decomposition, livestock and farming.

  1. 1. Fill in the blank: When __________ energy enters the Earth system than exits, the total amount of energy absorbed by Earth increases
  2. 3. When energy in the atmosphere hits this gas, it bounces off and can exit the Earth system back into space
  3. 4. When humans do this, the amount of carbon dioxide in the atmosphere increases, which causes more energy to be trapped in the Earth system. This causes Earth's temperature to increase.
  4. 5. General weather patterns over a LONG period of time, such as 50-100 years
  5. 6. When the amount of methane or carbon dioxide does this in the atmosphere, there is LESS energy in the Earth system and the temperature goes down
  6. 8. Fill in the blank: The Earth's atmosphere is made of multiple types of __________
  7. 10. This reflects energy away from Earth so it cannot be absorbed. More of this substance means less energy in Earth's system
