Answer:
Explanation:
•Material is buried in sediment and silt.
•Organic material decomposes
.Oxygen is used up or expelled.
•Heat and pressure are applied.
•Amount of heat dictates physical state of fuel
* Natural gas is forced into crevices or sedimentary rock pores.
For fossil fuels to form, the correct natural processes must play out in a geologic formation. Fossil fuels are sourced from materials that becomes buried in sediments usually in a sedimentary basin. In the basin, the organic material decomposes in the presence of oxygen. With increasing compaction and burial, the oxic environmental cuts off and the decomposition ceases. As burial continues, heat and pressure is applied to the formation and natural gas is produced. The amount of heat dictates the physical state of the fuel that would be produced be it solid, liquid or gas. The fuel is then forced into reservoir rocks through traps.
