As the methane (natural gas) rises it encounters a deep biosphere that consists of bacteria.
Conventional sources of energy usually include coal and oil - these have been used for many years. Natural gas is more recent, previously gas for cooking and lighting used to be made from coal. Coal has been used for centuries especially in Europe, whereas oil is a more recent development, mostly in the last century. Before that, transport was mostly fuelled by coal.
Oil
It is energy that won't last forever, or that will run out. An example of this is petroleum, which does form naturally, but only over thousands of years. At the rate at which humans use it, petroleum will most certainly run out before natural processes can replenish it.
Coal is a form of carbon.
Coal stores energy from the sun in the form of chemical energy
They are natural gas, petroleum&&coal=)
Coal, petroleum and natural gas took millions of years to form. Which is why they are classed as non-renewable resources.

Petroleum in any form, such as oil, natural gas, coal, etc.
coal is fuel. it can be burned to make heat or energy. the energy is coal was once sunlight energy that plants used. Petroleum and natural gas are also fuels. most scientists think natural gas petroleum form in a way similar to coal. however, they did not begin as plants. they began as small sea organisms. so, crude oil and natural gas are called fossil fuels.
Some are: coal, oil and natural gas. It took millions of years for them to form and if we use them up, there would not be enough time for them to form again.
Coal is plant matter ( tress from the Carboniferous ) and oil is from micro-organic matter.

where did petroleum come from?
