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 elemental composition?Exclusively carbon (C) and hydrogen (H) atoms, forming covalent bonds
2. What is the energy release mechanism?Combustion, an exothermic oxidation reaction releasing significant thermal energy
3. How do hydrocarbons become oil or natural gas?Oil and natural gas form when plant and plankton material gets buried under layers of rock. Over millions of years, heat and pressure turn that material into simpler hydrocarbons.
4. Why are hydrocarbons important besides fuel?Hydrocarbons are the raw materials for many everyday products like plastics, rubber, medicines, and fertilizers. They help make the world work.

Alkanes, Alkenes, Alkynes: Classes of hydrocarbons distinguished by the types of carbon-carbon bonds they contain (single, double, triple).
Aromatic Hydrocarbons: Hydrocarbons containing one or more benzene rings, known for their stability and distinct reactivity.
Petrochemical Cracking: A process that breaks down large hydrocarbon molecules into smaller, more useful ones, like those in gasoline and plastics.
