How were oil and natural gas created?

Answer 1

Oil and gas are created by heating and compression of thick layers of dead microscopic sea creatures (plankton), taking place deep underground and over millions of years.

Where undecayed organic material accumulates at shallow depths, it forms peat, which is the precursor to coal.

Answer 2

Oil and natural gas were formed from the remains of ancient marine organisms like algae and plankton that were buried under layers of sediment millions of years ago. Over time, heat and pressure transformed these organic remains into hydrocarbons, which became trapped in underground rock formations to create oil and natural gas deposits.
