Geoscience is an all-encompassing term used to refer to the earth sciences. Geoscientists strive to understand earth processes and study the origin and evolution of our planet; the chemical and physical properties of minerals, rocks, and fluids; the structure of our mobile crust; the history of life; and the human adaptation to earthquakes, volcanoes, landslides, and floods.
