Petroleum

The step needed for sea plants and animals to become hydrocarbons is

• enormous heat and pressure
• shallow burial by sediments
• refining and processing
• drilling and distillation

The job of an oil refinery is to

• transport the crude from the drill site
• separate crude into various types of fuel
• pump crude oil up to the surface
• mix separate types of fuel into crude

Distillation occurs where crude oil is separated into fuels by

• mixing it with corn starch and letting it settle
• putting it under intense pressure until it becomes solid
• heating it to different boiling points
• removing the sulfur particles from it
