Petroleum and natural gas form from the decay of radioactive sediments under ground plant material that collected millions of years ago in swamps the remains of plants and animals buried in seas long ago heating and cooling of magma in underground chambers

Option (3)

Explanation:

The petroleum and natural gas are two of the non-renewable resources that are formed from the burial of plants and animals about millions of years back. These are comprised of hydrocarbons that are very limited in amount and takes a long time to form. These are the fossil fuels on which the majority of the countries are directly dependent.

These are formed when the fossils were deposited in a shallow marine type of environment, detaching from the atmospheric environment.

For example, the deposition of plants and animals in the seas long time back gives rise to the formation of fossil fuel such as petroleum and natural gas.

Thus, the correct answer is option (3).
