Final answer:
The fossil fuel described as a solid is coal, the liquid is oil (petroleum), and the gas is natural gas.
Step-by-step explanation:
The fossil fuel that is described as a solid is coal. Coal is a black or brownish-black sedimentary rock that is primarily composed of carbon. It is formed from the remains of plants that lived and died millions of years ago.
The fossil fuel that is described as a liquid is oil, also known as petroleum. Oil is formed from the remains of marine organisms that were buried under layers of sediment and subjected to heat and pressure over millions of years.
The fossil fuel that is described as a gas is natural gas. Natural gas is mainly composed of methane and is formed from the remains of ancient marine organisms that were trapped in rock formations.
