EVERYDAY SCIENCE

Detailed explanation-1: -Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried. Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels.

Detailed explanation-2: -Natural gas and oil are formed from dead marine organisms. The tiny organisms die and sink to the bottom of the ocean, forming a layer of organic matter. Over time, sediment builds over the remains, and they get buried deeper and deeper. Then heat and pressure change the remains into oil or natural gas.

Detailed explanation-3: -Oil and gas are formed from organic material mainly deposited as sediments on the seabed and then broken down and transformed over millions of years. If there is a suitable combination of source rock, reservoir rock, cap rock and a trap in an area, recoverable oil and gas deposits may be discovered there.

Detailed explanation-4: -Formation and exploration of fossil fuels Gas and oil form in the sea over a period of millions of years, as the remains of animals and plants sink to the ocean floor. Combined with particles flushed from the land, they are buried and compressed into layers of sediment several kilometres thick on the ocean floor.
