Oil and Natural Gas
Oil and Natural Gas
• Oil– Formed from small, dead ocean organisms that
sink to the bottom and get covered by layers of rock and dirt
• Natural Gas– Methane– Cleanest of fossil fuels
HOW ARE OIL AND GAS MADE ???
Uses for Oil and Natural Gas
• Transportation (gasoline, diesel, jet fuel)• Asphalt• Heating• Cooking• Plastics• Lubricants
Oil Spills
• Accidental release of liquid petroleum (oil) into the environment
• Examples:– Oil ship wrecks– Leak in oil pipeline
Methods for Cleaning an Oil Spill
• Bioremediation: using microorganisms or biological agents to break down or remove oil
• Dredging: some oils sink, cleaning below the surface of the water
• Skimming: cleaning oil off of surface• Dispersion: materials, such as some detergents can
disperse oil into small clusters that may be easier to remove than larger areas
• Burning: Can eliminate large amount of oil in the water, but causes air pollutions
Materials• Rubber bands • Paper towel • String • Cotton ball • Plastic wrap• Popsicle sticks• Toothpick • Balloons • Suction tube • Spoon • Soap • Sand• Windex• Kitty litter
