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.
A long time
Coal is not a renewable resource beacuse it was formed by plants and rocks millions of years ago and cannot be remade it is considered a fossil fuel
No, diamond is a mineral. Coal is an igneous rock; it can take years for coal to form.
millions of years
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.

yes when during photosynthesis plants take co2 n whn they decomposed they form coal
millions of years
nocan not be replaced / takes a long time to form

No, coal took many millions of years to form, which makes it definitely non-renewable. That's because when it's all used up, there would be a long wait for more coal to form.
