Fracking collects natural gas that forms when organic matter is compressed under great temperature and pressure.
<h3>What is natural gas?</h3>
Natural gas is a mixture of gaseous hydrocarbons associated with petroleum deposits; mostly methane with smaller amounts of ethane, propane and butane; principally used as a fuel.
Natural gas is formed by the combination of compression and high temperature causing the carbon bonds in the organic matter to break down.
Therefore, it can be said that Fracking collects natural gas that forms when organic matter is compressed under great temperature and pressure.
