Coal is a finite resource because it is formed from fossilized plants and other organic materials that took millions of years to form under specific geological conditions. These materials were buried in sedimentary rock and subjected to high pressure and temperature, which led to the formation of coal. The process of coal formation is slow and cannot be replicated in human timescales, which means that once the coal deposits are depleted, they cannot be replenished within a short time frame. Additionally, coal mining activities can lead to environmental degradation and can harm local ecosystems, which further limits the availability of coal as a resource.
