Crude Oil and Hydrocarbons

• Where is crude oil found?


  In porous rocks in the Earth’s crust
• How is crude oil formed?


  it is formed over millions of years from the fossilised remains of plankton
• Is crude oil renewable or non renewable?


  Non renewable- it is a finite resource
• What is crude oil used for?


  To make the following:

  -dyes

  -fuels

  -plastics

  -fabrics

  -medicines
• What are the two conditions needed to produce crude oil?


  Heat and pressure
• Why is crude oil a finite resource?


  It takes millions of years to produce
• True or false; crude oil is made from dead sea organisms (plankton)


  True
• What are most of the compounds in crude oil?

  Hydrocarbons
• What are hydrocarbons?


  Molecules made of only carbon and hydrogen atoms
• The larger the hydrocarbon:


  -the more viscous it is (the less easily it flows)

  -the higher its boiling point

  -the less volatile it is and the less easily it ignites
• What affects the way hydrocarbons are used as fuels and their properties?


  Size
• What are fuels?


  substances that can be burned to release energy
• 3 factors which would affect how quickly we will run out of crude oil:


  -usage rates

  -discovery of new deposits

  -recycling rates
