Carbon in the Earth
What forms does carbon take on in the earth?
The main forms carbon takes on in the earth are diamonds, graphite, amorphous, fullerene and charcoal. Recently, a new form of carbon was made called 'nano-foam'. Nano-foam is a soft spongy form of carbon. This carbon is also magnetic. There is another form of carbon thought to exist called white carbon. It is the softest substance on earth which means that carbon can be the hardest substance (diamond) or the softest (white carbon).
By what processes does carbon leave and enter the earth?
Carbon leaves and enters the earth through the carbon cycle and a process called photosynthesis. Plants breathe in CO2, then they get eaten by animals. Both the plants and the animals break down in the earth, and over millions of years they turn into carbonic rock. Through processes such as extraction, and natural release, the carbon enters the atmosphere, and the cycle starts again.
