The natural material that is not a fossil fuel from the options provided is cotton. Cotton is a natural fiber derived from the cotton plant, while petroleum and natural gas are both fossil fuels, and vinyl is a synthetic material.

what must happen for a natural resource to become a synthetic material?

it needs to go through a phase change
it needs to be dried out
it needs to be pounded very thin
it needs to go through a chemical reaction

For a natural resource to become a synthetic material, it needs to go through a chemical reaction. This process often involves modifying the natural resource's chemical structure or combining it with other substances to create a new material with different properties.

what is a polymer?

a piece of a natural resource that has been broken down before it is recycled into new materials
a chain of repeating compounds found in both natural and synthetic materials
a natural resource formed on earth from plant or animal remains
a natural resource used to make synthetic materials

A polymer is a chain of repeating compounds found in both natural and synthetic materials. Polymers can be composed of large numbers of similar or identical structural units (monomers) that are bonded together, and they can be naturally occurring (like proteins and cellulose) or synthetic (like plastics).

how is plastic made?

coal and natural gas are broken down from long chains into smaller compounds we call plastic.
coal and natural gas are chemically broken down into small compounds that combine to form plastic.
oil and natural gas are chemically broken down into small compounds that combine to form plastic.
oil and natural gas are broken down from long chains into smaller compounds we call plastic

Plastic is made when oil and natural gas are chemically broken down into small compounds that combine to form plastic. In this process, the hydrocarbons from crude oil or natural gas are processed (often involving cracking and polymerization) to create the small molecules that make up plastic materials.
