describe the process of formation of petroleum . state the constituents of petroleum
Answers
A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has mostly been recovered by oil drilling.
Answer:
The organisms which lived in the sea got buried at the bottom of oceans. Over a period of time, their dead bodies were covered with sediments. Intense pressure and heat under the earth’s layers transformed these organisms into petroleum.
The basic molecules which are present in petroleum are carbon, nitrogen, oxygen, hydrogen etc. It is produced as a by-product of natural gas processing and petroleum refining. The components of LPG are gases that evaporate under normal temperature and pressure.
