Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the composition?Complex mixtures of hydrocarbons, varying by crude oil source
2. What is the primary refining process?Fractional distillation based on boiling point differences
3. What is petroleum?Petroleum is a natural liquid found underground that is made of many different kinds of hydrocarbons. When it is processed in refineries, it becomes fuels and other useful products.
4. How do refineries turn crude oil into gasoline?Refineries heat crude oil and let it rise through a tall column. The column separates the oil into parts that boil at different temperatures, and the part that boils at gasoline’s temperature is collected as gasoline.

Hydrocarbon: Organic compounds consisting entirely of hydrogen and carbon atoms, forming the basis of petroleum.
Fractional Distillation: A separation technique that exploits differences in boiling points to isolate components of a liquid mixture.
Cracking: A refining process that breaks down large, complex hydrocarbon molecules into smaller, more useful ones.
Petrochemicals: Pure chemical compounds derived from petroleum or natural gas, used as building blocks for plastics and other materials.
