1. Where do the extra greenhouse gases come from?
Nature: Human Activity? Both/Neither

2. Use the following slides and videos to complete:
Where do Greenhouses come from?
As you are reading or watching the videos write details as to how the sources emit the greenhouse gas.

3. Greenhouse Gases
Gases that trap heat in the atmosphere are called greenhouse gases.
Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products, and also as a result of certain chemical reactions (e.g., manufacture of cement). Carbon dioxide is removed from the atmosphere when it is absorbed by plants as part of the carbon cycle.
Methane (CH4): Methane is made during the production and transport of coal, natural gas, and oil. Methane is given off from livestock (cows, etc.) and other farming practices.
Nitrous oxide (N2O): Nitrous oxide is given off during farming and from factories, as well as during burning of fossil fuels.

4. What is a Fossil Fuel?
A combustible (can catch on fire) material, found deep in the Earth’s crust that has been under pressure for millions of years.
There are 3 types of Fossil Fuels found in Earth’s crust.
Natural gas
Coal
Oil

5. COAL Generating Electricity Coal is used for: Old coal furnaces
Old locomotives
Power generators at some factories
Making steel

6. Oil Oil is used for: Transportation fuels (gasoline)
Fuel oil for heating
Generating Electricity
Road oil (tar/asphalt)

7. Petrochemicals are products made from fossil fuels, mainly oil.
Man-made rubber
Plastics
cosmetics
WAX
medicine

8. Natural Gas Oldest fossil fuel Found deepest in Earth’s crust
Found as a gas
Made from decayed animals
Gas companies add a sulfur smell to the fluid so that you know it is their because it is natural invisible and odorless.

9. Natural Gas Household Uses
Heat water – hot water heaters
Heat homes – furnaces
Cooking – stoves
Drying clothes – clothes dryers
Everytime you use these things you are emitting CO2 into the atmosphere!

10. Fossil Fuel Disadvantages
Have a limited supply
(It takes a long time to create. So once we use it all up it is gone!)
When burning any fossil fuel it puts greenhouse gases such as CO2 and methane into the atmosphere.
(Increased levels of greenhouse gases causes Global Warming. )

11. Non Renewable Energy Resource
57% of your electricity comes from coal and natural gas!
Remember to turn out the lights!!!

12. Burning Fossil Fuels

13. FOSSIL FUELS

14. When you are using electricity you are emitting CO2 into the atmosphere!
Did you know most video game consoles use a lot of energy even when off. Most of them go into standby mode and do not shut completely down.
How much CO2 has Fortnite released into the atmosphere????

15. Think about ways we could reduce our use of fossil fuels.
(farming)
Think about ways we could reduce our use of fossil fuels.
(Factories)

16. Deforestation
Watch the video and add a short description of how deforestation contributes to Climate Change.

17. Forest fires and decaying plants and animals release Carbon into the atmosphere.
All living things are made of carbon. When they decompose or burn the carbon inside them is released as CO2.

18. Fire Reaction
FIRE
When fuel like wood is burned, carbon dioxide is produced.

19. Methane
Watch the video and write details about what releases Methane into the atmosphere.
