Natural gas is a mixture of gaseous hydrocarbons located under the surface of the earth, often near petroleum deposits; used as a fuel. Petroleum-liquid is a mixture of complex hydrocarbon compounds, used widely as a fuel source. Oil and natural gas are formed<span> from the remains of plants and animals. </span>
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.
The Agricultural Revolution of the 18th century paved the way for the Industrial Revolution in Britain. New farming techniques and improved livestock breeding led to amplified food production. This allowed a spike in population and increased health. The new farming techniques also led to an enclosure movement.
A geothermal power plant is the alternative energy generation technology that requires burning fossil fuels to start generating electricity.
<u>Explanation:</u>
A geothermal power plant derives its energy from the steam or from the heated up water that is present deep inside the surface of the Earth at some locations.
The presence of steam or hot water at such locations is due to the heat available in the interiors of Earth.
This heat is partially generated from the burning of fossil fuels that are present deep inside the Earth.
