Earth
science (also known as geoscience, the geosciences
or the Earth sciences) is an all-embracing term for
the sciences related to the planet Earth. The formal
discipline of Earth sciences may include the study
of the atmosphere, hydrosphere, oceans and
biosphere, as well as the solid earth. Typically
Earth scientists will use tools from physics,
chemistry, biology, chronology and mathematics to
build a quantitative understanding of how the Earth
system works, and how it evolved to its current
state. [Wikipedia]
