How is metal made in nature?
How is Metal Made? Most of the metal on Earth, especially iron, is found within the Earth's core. Metal is scattered unevenly throughout the Earth's crust, mixed with rock, and combined with oxygen and other elements. Some rock types, such as granite, only hold trace amounts of metal.
