  From remains of dead plants and animals
• What specific organisms contribute to the formation of crude oil?

  Plankton
• What conditions are necessary for the formation of crude oil?

  High pressures and temperatures
• How long does it take for crude oil to form?

  Millions of years
• Why is crude oil considered a finite resource?

  It takes a long time to form
• What term is used for fuels like coal, oil, and gas?

  Non-renewable fuels
• What is the purpose of fractional distillation?

  To separate different hydrocarbons
• What is the first step in fractional distillation?

  Heat the crude oil until it becomes gas
• What happens to the gaseous mixture in the fractionating column?

  It cools and condenses into liquids
• How do boiling points affect the separation of hydrocarbons?

  Higher boiling points condense first
• What are the uses of heavy fuel oil?

  Heating oil and lubricating oil
• What type of hydrocarbons are found at the top of the fractionating column?

  Shorter chain hydrocarbons

  Propane and butane
• Why are shorter chain hydrocarbons better fuels?

  They are more flammable
• What happens to longer chain hydrocarbons?

  They can be cracked into smaller hydrocarbons
