Because natural gas, which is mostly CH4, has a high hydrogen content, combustion of natural gas produces less CO2 for the same amount of heat produced from burning other fossil fuels. For example, for the same amount of energy produced, burning natural gas produces about half of the amount of CO2 produced by burning coal. There is an important asterisk here, though. It's not inconceivable that some dinosaurs perished in conditions that lent themselves to the formation of fossil fuels—so, theoretically, a tiny proportion of the world's oil, coal, and natural gas reserves could be attributed to rotting dinosaur carcasses. Just like other kerogens, coal produces oil and gas during its burrying in the underground, though in lesser quantities regarding oil. The methane issued from the process and which has remained adsorbed on the coal will be called… firedamp. Oil, natural gas, and coal are all fossil fuels meaning they come from the earth and are nonrenewable resources meaning they can be replaced but it takes very long as in many many years. With too much heat, the oil breaks down to make methane. This gas is also produced as coal forms. Coal, as a solid, mostly sits where it was formed. Eventually, if the rocks above it are eroded so that it is exposed at the Earth’s surface, the coal itself may be eroded away, and either “eaten” by bacteria, or buried in new rocks. Most carbon dioxide comes from the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide. Asked in Energy
Jun 29, 2018 Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals
Most sediments are deposited under water, or the spaces in them fill up with water later. Natural gas is gaseous (no surprise there!), oil is liquid and floats on water, and so both tend to move upward through the water-filled spaces. The great majority of oil and gas eventually reach the Earth’s surface as oil or gas seeps. 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. Coal, oil and gas are collectively called fossil fuels, because they formed from organic (living) matter. Coal was formed from the plants that grew on earth millions of years ago. Imprints of these plants are called fossils and often appear on lumps of coal and adjacent rocks. Coal oil is a shale oil obtained from the destructive distillation of cannel coal, mineral wax, or bituminous shale, once used widely for illumination.. Chemically similar to the more refined, petroleum-derived kerosene, it consists mainly of several hydrocarbons of the alkane series, with 10 to 16 carbon atoms in each molecule, with a boiling point of 175°C to 325°C, higher than gasoline or

May 31, 1999 Fossil fuels—the hydrocarbons known as peat, coal, oil, and natural gas—are formed from the constituents of deeply buried and preserved Jul 15, 2014 Indeed, the governments of Iraq, Nigeria, Russia, South Sudan, and Syria derive the great bulk of their revenues from oil sales, while the major Oct 25, 2013 Coal, natural gas and oil accounted for 87 percent of the world's primary energy consumption last year, the group reported in a new "Vital Signs Oct 14, 2011 Alternative energies won't replace oil, gas, and coal anytime soon. for decades to come: cost, the slow pace of energy transitions, and scale. “Global warming is fueled by oil, coal, and natural gas exports. Fred is deeply concerned about proposals to build the largest coal export terminal in has been quietly seeking permission to expand their export of tar sands-derived oil from Aug 8, 2011 Underground gas and oil, mixed with water, rise from a heated coal deposit until they are either trapped by an overlying rock formation or emerge Natural gas is produced from onshore and offshore natural gas and oil wells and from coal beds. In 2018, U.S. dry natural gas production was about 2% greater than U.S. total natural gas consumption. Five states accounted for about 68% of total U.S. dry natural gas production in 2018.
