Fossil Fuels such as coal, oil, and natural gas.
millions of years, if you're referring to oil/natural gas/coal made from dead plants and animals that have been compressed and heated underground. Swamps and bogs were main sources of this.
It is not known what, exactly, caused the Newcastle earthquake of 1989. Originally, investigations following the earthquake suggested that it was triggered by 200 years of underground coal mining. Geoscientists from Columbia University claimed that removal of 500 mega tonnes of coal and 2000 mega tonnes of water removed from the ground reactivated a major faultline underneath the Newcastle's coalfields. Removal of millions of tonnes of coal, and the pumping out of water needed in the mining process, created enough stress to reactivate a fault line beneath the Newcastle coal fields. However, a 2007 report cast doubts on this theory, which came from a US report. Australian geoscientists believe more factors were involved, as evidenced by the fact that minor earthquakes have occurred in the Hunter Valley coal mining region from time to time, and not necessarily close to the coal mining sites. The epicentre of the quake was simply too far underground to have been caused by coal mining alone. For more details on possible causes of the Newcastle earthquake, see the link below.
Ferns were the dominant form of vegetation during the Carboniferous Period about 300 million years ago. They were much larger than ferns growing today, some reaching a height of 24 meters (80 feet). Much of the world's supply of coal, oil, and gas formed from the remains of ancient ferns that were slowly buried under layers of sediment.

Coal is formed from dead plant matter that was buried and subjected to high pressure and heat over millions of years. This process transformed the plant material into coal through a process known as coalification.
Millions and millions of years.
Coal is a fossil fuel that forms from the remains of plants that lived millions of years ago in swampy environments. Over time, these plant materials were buried and subjected to high temperatures and pressures, which caused them to transform into coal.
millions of years
No, not in our lifetime. It takes millions of years to form coal.
It typically takes millions of years for coal to form. Coal is created from the remains of plants and trees that were buried under layers of sediment and subjected to heat and pressure over long periods of time.
Coal is a fossil fuel created from the remains of ancient plants that have been buried and subjected to high pressure over millions of years. The carbon in the plants is preserved in the form of coal after this process of transformation.
The process of compressing plant matter to make coal takes millions of years.
100 million years (APEX) ;)
Coal is a nonrenewable resource. It is nonrenewable because it takes millions of years to form.
Coal takes millions of years to form from the pressure of dead plants and trees in swamps.
Coal can last for millions of years, as it is a fossil fuel formed from the remains of plants that lived in swamps millions of years ago. However, once coal is mined and burned, its energy is used up and it cannot be reused.
