Amorphous carbon is formed when a material containing carbon is burned without enough oxygen for it to burn completely.This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.
Diamond, the third naturally occurring form of carbon, is one of the hardest substances known.Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.Naturally occurring graphite occurs in two forms, alpha and beta.In actual case studies, millet and maize eaters can easily be distinguished from rice and wheat eaters.Studying how these dietary preferences are distributed geographically through time can illuminate migration paths of people and dispersal paths of different agricultural crops.In conclusion of my research, I can tell you that the standard value for the half life of Carbon-14, or radiocarbon, is 5,730 years.

Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.It is a transparent material that can split a single beam of light into two beams, a property known as birefringence. Large molecules consisting only of carbon, known as buckminsterfullerenes, or buckyballs, have recently been discovered and are currently the subject of much scientific interest.A single buckyball consists of 60 or 70 carbon atoms (C) linked together in a structure that looks like a soccer ball.Although carbon-14 decays into nitrogen-14 through beta decay, the amount of carbon-14 in the environment remains constant because new carbon-14 is always being created in the upper atmosphere by cosmic rays.
