Geology and Minerals
Earth science or geoscience includes all fields of natural science related to planet Earth. This branch of science deals with the complex physical, chemical, and biological constitutions and synergistic linkages of Earth's four spheres: the biosphere, hydrosphere/cryosphere, atmosphere, and geosphere (or lithosphere). Earth science can be generalized into planetary science, a more recent branch of science.
