उत्तर
The coal is formed by compression of Carboniferous age forests between impervious sedimentary rock-folds and the petroleum is the stored ‘body oil of dinosaurs of the Jurassic period in between the impervious rocks within the poses of shale rocks. So these are called the fossil fuels on account of being buried within the rocks like the fossils for a long period under the pressure of tectonic forces.
