Natural gas is a mixture of gaseous hydrocarbons located under the surface of the earth, often near petroleum deposits; used as a fuel. Petroleum-liquid is a mixture of complex hydrocarbon compounds, used widely as a fuel source. Oil and natural gas are formed<span> from the remains of plants and animals. </span>
The petroleum and natural gas are two of the non-renewable resources that are formed from the burial of plants and animals about millions of years back. These are comprised of hydrocarbons that are very limited in amount and takes a long time to form. These are the fossil fuels on which the majority of the countries are directly dependent.
These are formed when the fossils were deposited in a shallow marine type of environment, detaching from the atmospheric environment.
For example, the deposition of plants and animals in the seas long time back gives rise to the formation of fossil fuel such as petroleum and natural gas.
Negative: the ice is melting meaning sea levels are rising. if sea levels are rising then there is less land. if there is less land then there is less land to be able to farm on
The Richter scale is used, from 0.1 to 9.0 magnitude. The Richter scale is determined from the logarithm of the amplitude of waves recorded by seismographs.
