Fossil Fuels and Their Formation

The video tutorial explores the origins and formation of fossil fuels, including coal, petroleum, and natural gas. It explains how these fuels are formed from the remains of plants and animals over millions of years, under heat and pressure. The tutorial also covers the combustion process of fossil fuels and their various uses, such as in energy production and manufacturing. Key concepts include the types of fossil fuels, their formation processes, and the chemical reactions involved in their combustion.

What is the primary source of fossil fuels?
