Clay minerals are also silicate minerals (see previous pie-chart) that form through the processes involved with weathering of pre-existing silicate minerals in the presence of weak acid and water. As rain forms in the atmosphere, it combines with carbon dioxide to form a weak acid called carbonic acid with the chemical formula, H 2 CO 3 .
