What are Fossil Fuels ? What creates them ? Three main types of Fossil Fuels A combustible material created naturally beneath Earths surface over a LONG period of time. Decayed plant an animal matter. Coal, Natural Gas and Petroleum
Where does natural gas come from?
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.
Coal Is the youngest of the fossil fuels and lies closest to the Earths surface. We remove it through underground mining.
Oil Sometimes called: Petroleum Crude oil Is the 2 nd 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)
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?
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
Natural Gas Household Uses Heat water – hot water heaters Heat homes – furnaces Cooking – stoves Drying clothes – clothes dryers Other household appliances
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. Propane, ethane, water, etc. Gas continues through pipelines Compressor stations to maintain pressure Compressor stations to maintain pressure Can be stored underground in old wells For later use For later use Distributed to customers through pipelines.
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
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 Smog, acid rain, greenhouse gas emissions
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 heat water, fuel stoves, clothes dryers, furnaces, other household appliances
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.
What is Global Warming? Global warming computer game Global warming computer game Global Warming is the gradual increase of earths temperature. Greenhouse gasses like CO2 enters the atmosphere and traps heat around the earth.
Why is Global Warming bad? video and info site An increase in Earths temperature can cause the polar icecaps to melt. Changes weather patterns: Floods, hurricanes, tornados, effects some biotic factors natural timing.
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?
