All three were formed many hundreds of millions of years ago before the time of the dinosaurs - hence the name fossil fuels. The age they were formed is called the Carboniferous Period. It was part of the Paleozoic Era. "Carboniferous" gets its name from carbon, the basic element in coal...
Fossil fuels are storehouse of energy and are used abundantly in industries, thermal power plants, and transportation. However, these fuels cause irreparable damage to the environment. Smoke released by burning fossil fuels contain carbon, nitrogen and sulfur which react with atmospheric oxygen to for...

One of the big unknowns in forecasting the course ofclimate changeis anticipating how the Earth’scarbon cyclewill respond to the coming man-made increase in temperature. Thecarbon cycledescribes the many processes through which carbon flows between stocks of the element in theatmosphere, the ocean...
Hence, we conclude that the microbodies examined herein are indeed the fossilized remains of colour-bearing organelles and that they contain high concentrations of the living organism's original chemistry; that is, components of melanin derived from the pigments of the eye. From our ToF-SIMS ...
element is intended, such intent will be explicitly recited in the claim, and in the absence of such recitation no such limitation is present. For non-limiting example, as an aid to understanding, the following appended claims contain usage of the introductory phrases “at least one” and “...
Solid fossil fuels contain a large amount of trace elements, the weights of which in most cases exceed or are commensurate with their quantities purposefully extracted from ore raw materials. It is possible to obtain raw materials enriched in trace elements by the processing of solid fossil fuels...
But while hydrogen is the most abundant element in the universe, it generally exists combined with other molecules. Currently, commercial hydrogen is produced in an energy-intensive process almost entirely powered by fossil fuels. A rainbow of colors is used as a shorthand for the different types...
Nowadays, supermarkets are expected to install glass doors to cover the cooled product displays in order to contain the cold. A direct consequence of this is the necessity to mechanically cool the sales floor to prevent unwanted condensation on the cold surface of the glass doors. Energy balance...
Power and heat generation by combustion of these fossil fuels are some of the largest sources of airborne metals, sulfur oxides, and PM2.5. Many of the particles resulting from these sources’ emissions are also as ultrafine nanoparticles, which can be especially toxic due to their small size ...
