why do they call oil and natural gas fossil fuels
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? April 20, 2016 Energy Quest The information on this page comes from Energy Quest. Where Fossil Fuels Come From: There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs hence the name fossil fuels. The age they were formed is called the Carboniferous Period. It was part of the Paleozoic Era. "Carboniferous" gets its name from carbon, the basic element in coal and other fossil fuels.

Some scientists say that tiny diatoms are the source of oil.
Diatoms are sea creatures the size of a pin head. They do one thing just like plants; they can convert sunlight directly into stored energy. In the graphic on the left, as the diatoms died they fell to the sea floor (1). Here they were buried under sediment and other rock (2). The rock squeezed the diatoms and the energy in their bodies could not escape. The carbon eventually turned into oil under great pressure and heat. As the earth changed and moved and folded, pockets where oil and natural gas can be found were formed (3). Oil has been used for more than 5,000-6,000 years. The ancient Sumerians, Assyrians and Babylonians used crude oil and asphalt ("pitch") collected from large seeps at Tuttul (modern-day Hit) on the Euphrates River. A seep is a place on the ground where the oil leaks up from below ground. The ancient Egyptians, used liquid oil as a medicine for wounds, and oil has been used in lamps to provide light.

Many early writers described the natural petroleum seeps in the Middle East, especially in the Baku region of what is now Azerbaijan. The gas seeps, probably first ignited by lightning, provided the fuel for the "eternal fires" of the fire-worshiping religion of the ancient Persians. Natural gas is lighter than air. Natural gas is mostly made up of a gas called methane. Methane is a simple chemical compound that is made up of carbon and hydrogen atoms. It's chemical formula is CH4 one atom of carbon along with four atoms hydrogen. This gas is highly flammable. Natural gas is usually found near petroleum underground. It is pumped from below ground and travels in pipelines to storage areas. The next chapter looks at that pipeline system. Read more at: http://www. energyquest. ca. gov/story/chapter08. html
