Clay minerals are not much to look at, but life on Earth depends on them. At the microscopic level, clays are tiny flakes, like mica but infinitely smaller. At the molecular level, clay is a sandwich made of sheets of silica tetrahedra (SiO 4 ) and sheets of magnesium or aluminum hydroxide (Mg(OH) 2 and Al(OH) 3 ).
