Question

Quizplus · Accepted Answer

The incomplete decomposition of organic matter is the earliest step in the formation of fossil fuels. This occurs when dead plants and animals are buried under sediment and are prevented from decomposing fully due to lack of oxygen or other nutrients. As more sediment accumulates, the pressure and heat increase, eventually leading to the formation of fossil fuels such as coal, oil, and natural gas. The other options, such as subjecting organic matter to extreme pressure or heat, are later steps in the process. Flooding swamps with seawater may contribute to the formation of certain types of fossil fuels, but it is not a necessary step in the overall process.
