1. Fossil Fuels

2. A combustible material created naturally beneath Earth’s surface over a LONG period of time.
Decayed plant an animal matter.
Coal, Natural Gas and Petroleum
What are Fossil Fuels ?
What creates them ?
Three main types of Fossil Fuels

3. Where does natural gas come from?

4. Where do Fossil Fuels Comes From?
Decayed plants and animals
Millions of years ago
Created thick layers of organic material
Over time
Mud and soil created rocks above the organic material (decayed plants and animals)
Pressure and heat
Changed some organic material into natural gas.

5. Coal
Is the youngest of the fossil fuels and lies closest to the Earth’s surface.
We remove it through underground mining.

6. Oil
Sometimes called:
Petroleum
Crude oil
Is the 2nd oldest fossil fuel. It is found deeper into the earth and is a fluid.
It is obtained by drilling deep into the earth. (oil well)

7. Natural Gas
Natural Gas is the oldest and deepest Fossil fuel and is colorless and odorless.
Gas companies add a sulfur smell to the fluid.
Why is this important?

8. Pair/share What are Fossil Fuels made from?
What are the three types of fossil Fuels?
Can fossil fuels be replaced easily?
Decayed plant and animal matter
Natural Gas, Oil and Coal
No they take billions of years to replace

9. Natural Gas Household Uses
Heat water – hot water heaters
Heat homes – furnaces
Cooking – stoves
Drying clothes – clothes dryers
Other household appliances
Natural Gas Household Uses

10. How Natural Gas Gets To You
Pumped out of the ground using oil wells
Then transported in Pressurized pipelines to a natural gas facility.
At the facility they remove unneeded materials and liquids
Propane, ethane, water, etc.
Gas continues through pipelines
Compressor stations to maintain pressure
Can be stored underground in old wells
For later use
Distributed to customers through pipelines.

12. Pair/Share What are 4 ways we use Natural Gas in the household.
What are 3 ways you can conserve Natural Gas in your home?
Heat water – hot water heaters
Heat homes – furnaces
Cooking – stoves
Drying clothes – clothes dryers
Other household appliances

13. Natural Gas Advantages
Underground pipelines are safe, reliable and protected from the weather
Cleaner burning than other fossil fuels, like coal and oil.
Increased use can address several environmental concerns
Smog, acid rain, greenhouse gas emissions

14. Natural Gas Popularity
Because of advantages, increasingly popular in U.S.
More than 62% of homes use natural gas
heat water, fuel stoves, clothes dryers, furnaces, other household appliances

15. Natural Gas Disadvantages
It takes a long time to create. So once we use it all up it is gone!
Have about 100 years supply of natural gas left at current levels of pumping
When burning Natural Gas it puts CO2 into the atmosphere.
Increased levels of CO2 causes Global Warming.

16. Global Warming is the gradual increase of earth’s temperature.
Greenhouse gasses like CO2 enters the atmosphere and traps heat around the earth.
What is Global Warming?
Global warming computer game

18. Why is Global Warming bad?
video and info site
An increase in Earth’s temperature can cause the polar icecaps to melt.
Changes weather patterns: Floods, hurricanes, tornados, effects some biotic factors natural timing.

19. What can you do?
What are 3 ways you can conserve natural gas in your home?
If we continue to use Natural gas at the rate we are using it, when do they predict we will run out?
