Geochemistry
Geochemistry (pronounced: jee-oh-kem-is-tree) is the branch of Earth Science that applies chemical principles to deepen an understanding of the Earth system and systems of other planets.
Etymology
The term "Geochemistry" is derived from the Greek words "Geo" which means Earth and "Chemistry" which is the scientific study of the properties and behavior of matter.
Definition
Geochemistry involves the study of the chemical composition of the Earth and other planets, chemical processes and reactions that govern the composition of rocks and soils, and the cycles of matter and energy that transport the Earth's chemical components in time and space.
