Omschrijving

Coal is burned to make electricity. Iron is used to make steel. Electrical wiring is made from copper. Stone and sand are needed for building. These important materials and others like them make our lives easier, but they are not easy to get because they have to be dug out of the ground. The first miners used picks and shovels. Mining has changed a lot since then.
