Chemist Chemistry is the study of the different elements which make up our world, and how they interact to form the world around us.
Earth science relies heavily on chemistry.
Our ability to measure these compounds, many of which are present in very small amounts, relies on the developments of chemical techniques and our ability to apply them from the surface, balloons, aircraft, and satellites. Examples of important Earth science problems whose study requires knowledge of chemistry include the formation of atmospheric aerosols from volcanic eruptions and industrial pollution, destruction of ozone from industrially produced molecules such as chloro-fluorocarbons, and global air pollution from fossil fuel combustion and biomass burning.
