GENERAL GEOLOGY

Detailed explanation-1: -Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels. Coal, natural gas, and petroleum are all fossil fuels that formed under similar conditions.

Detailed explanation-2: -Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.

Detailed explanation-3: -Petroleum and natural gas are formed from the dead remains of marine organisms that were buried under the sea. High temperature, high pressure, and absence of air over million of years transform these dead organisms into petroleum and natural gas.

Detailed explanation-4: -High temperature, high pressure and absence of air favor production of petroleum form dead organic matter.
