Natural gas

    Natural gas was formed millions of years ago by the earth's movement, tiny sea plants and animals, and sunlight. Natural gas has been found in underground rock cavities. It often seeps to the surface.
   Gas was produced by the chemical action of small sea plants and animals. The movement of the Earth's crust caused this material to be buried and subsequently to decay. Most natural gas consists mainly of METHANE, a combustible
   The deposits of natural gas are reached by drilling wells. Geologists are able to determine by soundings and by rock formations its approximate location. Fuel gas, gasoline, ink, synthetic rubber, perfume, drugs, and dyes are some of the natural gas products.
