Coal, oil, and natural gas are collectively classified as what type of energy resource, since they formed from the remains of ancient organisms over millions of years?

Explanation

Coal, oil, and natural gas are collectively classified as fossil fuels, since they formed deep underground over millions of years from the compressed and chemically transformed remains of ancient plants and other organisms. Because they take such an extraordinarily long time to naturally form, fossil fuels are considered non-renewable resources on any meaningful human timescale, meaning current global reserves are gradually being depleted through ongoing extraction and use. Burning fossil fuels for energy releases stored carbon dioxide into the atmosphere, making them a significant focus of efforts to reduce global greenhouse gas emissions.
