Fossil fuel any of a class of materials of biological origin occurring within the Earth's crust that can be used as a source of energy. Fossil fuels include coal, natural gas, petroleum, shale oil, and bitumen.
Fossil Fuel Any hydrocarbon deposit that can be burned for heat or power, such as petroleum, coal, and natural gas.
Fossil Hardened remains or traces of plant or animal life from a previous geological period preserved in the Earth's crust.
[edit] Fossil fuels
Carbon dioxide variations over the last 400,000 years, showing a rise since the industrial revolution.
carbon-based resources The recoverable fossil fuel (coal, gas, crude oils, oil shale, and tar sands) and biomass that can be used in fuel production and consumption.
Human activities such as deforestation and the burning of fossil fuels have increased the concentrations of greenhouse gases in the atmosphere.
It is formed along with coal and oil in fossil fuel deposits, and released to the atmosphere on mining. Methane is itself burned as a fuel, being the major constituent of natural gas. The atmospheric mixing ratio of methane is currently about 1.
In the past 200 years (since the Industrial Revolution) the increased burning of fossil fuels has released vast amounts of carbon dioxide into the atmosphere.
(Carbon Monoxide) A colorless, odorless gas resulting from the incomplete combustion of fossil fuels. Over 80% of the CO emitted in urban areas is contributed by motor vehicles.
acid rain- rain with an abnormally high acid content caused by burning of fossil fuels, which release sulfur and nitrogen oxides.
The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
the global temperature is changed 33 degrees Celsius, or 59 degrees Fahrenheit warmer than it would otherwise be. Some scientists think that the increase in greenhouse gases in the atmosphere (caused by pollution- mainly the burning of fossil fuels ...
boundary layer) near the surface where the following conditions persist for at least 4 days: wind speeds less than 17 mph (poor ventilation), no frontal passages (change in air mass), and no precipitation (washout). Under these conditions, fossil ...
