The oxygen in the air combines with the minerals and the rocks change because the minerals are oxidizing. Oxidation can cause new chemical compounds such as iron oxide to form in the rocks.
Igneous rocks are formed from molten lava being cooled down. Metamorphic rocks start as igneous rocks and change form. Sedimentary rocks form from layers in the earths crust.
