In the rock of the lithosphere, carbon commonly occurs as carbonate minerals containing calcium or magnesium. It is also found as fossil fuels in coal and petroleum and gas. Native forms of carbon are much rarer, requiring pressure to form. Pure carbon exists as graphite or diamond.

Answer:
Carbon is present in the form of its compounds.
Explanation:
In the Earth's crust, elemental carbon is present only in a small amount. But, carbon compounds can be found abundantly. Compounds of carbon like carbonates of magnesium and calcium form common minerals such as magnesite, dolomite, marble, or limestone. Coral and the shells of oysters and clams are also abundant with calcium carbonate.
