Nature
Earth science is the study of what our planet is made of, how it has changed over time and how its systems interact, including the oceans and its magnetic field. Geochemists can apply their skills and knowledge to study the chemistry of meteorites and other samples of space rock (cosmochemistry) as well as using telescopes to study the chemistry of material in space (astrochemistry). Atmospheric science is the scientific and mathematical study of the Earth's atmosphere, climate, and weather.
