why is petroleum called a fossil fuel

Fossil fuels The Industrial Revolution in Europe in the
19th century fired man s search for alternative sources of fuel to meet energy needs
of the mushrooming industries. With the realization that fossil fuels could meet this
requirement, the energy needs of the world were fulfilled for the time being. Fossil fuels are called so because they
have been derived from fossils, which were formed millions of years ago during the time of
the dinosaurs. They are fossilized organic remains that over millions of years have been
converted to oil, gas, and coal. Because their formation takes so long, these sources are
also called non-renewable. These fuels are made up of decomposed plant
and animal matter. When plants, dinosaurs, and other ancient creatures died, they
decomposed and were buried, layer upon layer under the ground. Their decomposed remains
gradually changed over the years. It took millions of years to form these layers into a
hard, black rock-like substance called coal, a thick liquid called oil or petroleum, and
natural gas the three major forms of fossil fuels.

Fossil fuels are usually found below
ground. Coal is either mined or dug out while oil and natural gas are pumped out. Coal is
widely distributed and is easier to locate than oil and gas. Fossil fuels take millions of years to
make, but burn and disappear in seconds. Once they are used, they cannot be reused. People
have irretrievably damaged the planet by extracting and burning these fuels. It is best
not to waste fossil fuels as they are not renewable. We have to learn to conserve these
sources of energy. Every year, millions of tonnes of coal is
consumed as energy. This has led to global warming (greenhouse effect) and the depletion
of resources. At present, the worldwide burning of coal,
oil, and natural gas releases billions of tonnes of carbon dioxide (measured as carbon)
into the atmosphere every year. Burning any fossil fuel means pollution of some sort.

if the fuel is low in sulphur, the atmosphere contains nitrogen, which combines with
oxygen at the high burning temperatures found in boilers, jet, or car engines. This yields
nitrogen oxides, which like sulphur dioxide, dissolves in rain to form nitric acid. Both
gases are poisonous to humans. Mining and exploration for fossil fuels can
cause disturbance to the surrounding ecosystem. The burning of fossil fuels emits oxides
of sulphur and nitrogen into the atmosphere. For more information on Fossil

Fossil fuels are non-renewable energy sources that formed more than 300 million years ago during the Carboniferous Period - long before. Fossil fuels are made up of and animal matter. When plants and animals died, their bodies decomposed and were buried under layers of earth. Millions of years later we have the three forms of fossil fuel: oil, natural gas and coal. Oil is a thick, black, gooey liquid also called petroleum.

It's found way down in the ground, usually between layers of rock. To get oil out, a well is dug. Digging a well is like putting a straw into a. The oil is then pumped out of the ground, just like when you suck pop up the straw. Oil is carried in pipelines and large tanker ships. A refinery changes the oil into products like gasoline, jet fuel and diesel fuel. It's also burned in factories and power plants to make. The oil is burned, which produces gases that turn a turbine to create electricity. Natural gas is lighter than air. Natural gas is made out of methane, which is a simple chemical compound made up of carbon and hydrogen atoms. This gas is highly flammable, so no near it. Natural gas is found near oil in the ground. It's pumped, just like oil, from wells that tap into the source and send it to large pipelines. Because you can't smell or see natural gas, it is mixed with a chemical to give it a stinky smell - like rotten eggs.

That way, it's easy to tell if there's a leak. After the stinky chemical is added, the natural gas is sent through underground pipes which go to your home so you can cook food and heat your house. It's also sent to factories and power plants to make electricity. Natural gas is burned to produce heat, which, creating steam, which passes through a turbine to generate electricity. Coal comes in several different forms from hard black rocks (that's the kind you get in your stocking at ) to soft brown dirt. Some forms burn hotter and cleaner than others. Coal is used to create more than half of all the electricity made in the US. In the states, many of the coal beds are near the. We get to the coal by mining for it. Most coal is transported by trains to power plants where it's burned to make steam. The steam turns turbines, which produce electricity. Do you know how your home is heated? Or do you live in a grass hut and don't need electricity?
