- Petroleum is again a carbon-rich compound formed by the decomposition of diatoms.
- Petroleum products are predominantly used to run automobiles.
- It is made of methane (carbon) and is lighter than air.

Disadvantages of using Fossil fuels
- Air pollution: Burning of fossil fuels generate a lot of chemicals like oxides of sulfur, carbon and nitrogen and release it into the atmosphere.
- Acid Rains : These chemicals fall back on earth as acid rain. They are very detrimental to natural and built environments.
- Greenhouse Effect and Global warming : Burning of fossil fuels release gases like carbon-di-oxide which trap the heat in the atmosphere without releasing it and causing temperatures to increase steadily.
