Metal
When the earth was formed the molten mass contained the many different metals which today we extract and use in huge quantities. Most of the metals combined with rock when molten, to form metallic ores. Metals can be divided into two main groups: ferrous metals are those which contain iron and non-ferrous metals that are those which contain no iron.
Metals are used in our daily lifes in various manufacturing process such as cookware, vehicles, jewelry, weapons, construction, electronic devices and many more.
