Final answer:
Coal, natural gas, and petroleum are the fossil fuels that pose risks to the environment.
Step-by-step explanation:
The fossil fuels that pose risks to the environment include:
- Coal: Extraction of coal can leave mountaintops bare and contaminate local water sources.
- Natural gas: Natural gas wells, including fracking sites, often leak methane into the atmosphere.
- Petroleum: Oil spills from accidents or natural disasters during extraction can be devastating to the environment.
These fuels have significant impacts on the environment through extraction, transportation, and production processes.
