Most coal comes from the Carboniferous period, which ended 290 million years ago.
Low grade lignite coals can form in a few thousand years or sometimes less, but they still contain some water and burn very poorly.
It takes millions of years for coal to form naturally. Coal is formed from plant material that undergoes a process of gradual burial, compaction, and chemical changes through heat and pressure over a long period of time.
100 Million years
Coal is a non-renewable energy source because it takes millions of years to form from the remains of plants and animals. Once it is extracted and burned to generate energy, it cannot be replaced within a human lifetime.
Coal can last for quite a long time when used in large amounts.
it can be sedimentary rocks
coal
No, not in our lifetime. It takes millions of years to form coal.
Coal typically takes millions of years to form. It is created through the transformation of plant material under high pressure and heat over prolonged periods of time.
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.
It is nonrenewable because it takes millions of years to form.
It takes millions of years for coal to form naturally. Coal is formed from plant material that undergoes a process of gradual burial, compaction, and chemical changes through heat and pressure over a long period of time.
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.
it takes millions of years to form but last only seconds when burning
Coal is non-renewable because it takes millions of years to form from the remains of plants and trees that were buried and compressed. Once coal is extracted and burned, it cannot be replaced on a human timescale, making it finite and non-renewable.
When coal is burned, chemical energy changes to thermal energy. The energy of sunlight was stored in the organic molecules of dead plants, which were compressed and altered to form long-chain hydrocarbons. Burning the coal oxidizes these molecules, releasing heat.
It is Non-Renewable because you can't use coal again because it takes millions of years for it to form.
