silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. in spite of its simple chemical formula, sio2, silica exists in many different forms. silica is found commonly in the crystalline state but occurs also in an amorphous state resulting from weathering or plankton fossilisation.
