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 PetroleumWhat are Fossil Fuels ?What creates them ?Three main types of Fossil Fuels
4 Where do Fossil Fuels Comes From? Decayed plants and animalsMillions of years agoCreated thick layers of organic materialOver timeMud and soil created rocks above the organic material (decayed plants and animals)Pressure and heatChanged some organic material into natural gas.
5 CoalIs the youngest of the fossil fuels and lies closest to the Earth’s surface.We remove it through underground mining.
6 OilSometimes called:PetroleumCrude oilIs 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 GasNatural 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 matterNatural Gas, Oil and CoalNo they take billions of years to replace
9 Natural Gas Household Uses Heat water – hot water heatersHeat homes – furnacesCooking – stovesDrying clothes – clothes dryersOther household appliancesNatural Gas Household Uses
10 How Natural Gas Gets To You Pumped out of the ground using oil wellsThen transported in Pressurized pipelines to a natural gas facility.At the facility they remove unneeded materials and liquidsPropane, ethane, water, etc.Gas continues through pipelinesCompressor stations to maintain pressureCan be stored underground in old wellsFor later useDistributed 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 heatersHeat homes – furnacesCooking – stovesDrying clothes – clothes dryersOther household appliances
13 Natural Gas Advantages Underground pipelines are safe, reliable and protected from the weatherCleaner burning than other fossil fuels, like coal and oil.Increased use can address several environmental concernsSmog, acid rain, greenhouse gas emissions
14 Natural Gas Popularity Because of advantages, increasingly popular in U.S.More than 62% of homes use natural gasheat 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 pumpingWhen 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 siteAn 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?
