Geology
From Palaeos.org
Geology ("to speak about the Earth") is a scintific discipline that focuses on the structure, composition, topology, history and changes the Earth has gone and is going through. Geology overlaps with chemistry when it comes to analyzing things such as buried organic remains. It overlaps with physics when it comes to understanding terrestrial properties such as the magnetic field. Paleontology is an example of how biology and geology come together. Together with meteorology and oceanography, it is a component of geoscience (also known as Earth science.)
Origins
Many metals such as gold, iron and copper were extracted from their ores through a process known as "smelthing" during ancient times.
