Fossil fuels are the remains of long dead plants that were buried in sediment tens to hundreds of millions of years ago (coal being made primarily from land plants and petroleum from plankton and algae). Drinking ethanol (which is usually just called alcohol) is made from the fermented sugars of plants (grains like barley, wheat, rye corn, or rice; fruits like grapes or apples; vegetables like sugarcane or agave; or the nectar of plants collected by bees called honey). The carbon in the ethanol that came from plants will be relatively rich in C are not.This means that the ethanol you might put inside yourself (the ethanol you might drink) will be slightly radioactive, while the ethanol you'd never consume (the ethanol you might wipe your skin with) will not be.Bacteria, fungi, and animals eat these plants and each other.In this way, atmospheric carbon is distributed throughout the web of life until every living thing has the same ratio of C as the atmosphere. Plants and animals tend to favor lighter nuclei just a bit.There are several other dating techniques that rely on the principle of exponential decay and half-life. This dating method is also known as Archaeological Dating or Historical Chronology. These methods were relied on especially prior to the introduction of scientific methods of dating.The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.

Even when the absolute dates are available, we have to supplement the information with relative dating.By 1965, atmospheric C concentrations were double their pre "atomic age" values.Coal and petroleum are the fuels that powered the Industrial Revolution.These highly energetic nuclear bullets wreak havoc on the atoms in the upper atmosphere: tearing electrons from their orbitals and setting them free, knocking neutrons and protons from the tight confines of the nucleus and setting them free, generating x-rays and gamma rays as they decelerate, and creating exotic particles like muons and pions directly from their excessive kinetic energy.
