How is Coal Formed? The formation of coal takes millions of years, which is why it is an exhaustible and non-renewable natural resource. It was formed around 300 million years ago when the earth was covered with swampy forests. When plants in these forests- mainly trees, mosses, ferns, and reeds died, they fell into the swamps.
