What are plastics made from?

Explanation:
Plastics are made from hydrocarbons, specifically long-chain polymers built from carbon-and-hydrogen monomers derived from fossil fuels like crude oil or natural gas. Through processes such as cracking and polymerization, these hydrocarbon molecules—examples include ethylene, propylene, and styrene—are linked to form plastics like polyethylene, polypropylene, and polystyrene. Water, silicates, and metals do not serve as the base building blocks for these synthetic polymers, which is why hydrocarbons are the correct source.
