Crude Oil and Hydrocarbons

• Crude Oil is formed over millions of years from what?

  The fossilised remains of plankton
• Crude Oil is found where?

  In porous rocks in the Earth's crust
• Crude Oil is a finite resource (non-renewable) that is used to produce fuels and other chemicals
• Most of the compounds in crude oil are what?

  Hydrocarbons
• What are Hydrocarbons?

  Molecules made of only carbon and hydrogen atoms
• Hydrocarbon molecules vary in size , which affects their properties and how they can be used in fuels
• The larger the Hydrocarbon

  The more viscous it is (less easily it flows), the higher the boiling point, the less volatile it is, the less easily it ignites
• What are Fuels?

  Substances that can be burned to release energy
