Earth Science involves the study of physical, chemical, and biological processes on Earth and other planets over time. We study not only rocks and minerals, but also rivers and oceans, ice and snow, and the atmosphere and climate. We are interested in the origins of the solar system, in the internal processes of planetary bodies, in the evolution of life on Earth and other planets, in understanding processes occurring on Earth today and in the distant past, and in understanding what lies ahead for the future of our planet. Earth Scientists explore, understand, and monitor the Earth to protect it and the people who live on it. Our students find employment in a wide array of professions, including law, business, policy, writing, education, medicine, science, art, and engineering. A background in Earth Science is unique in that it combines many fields into a unified physical science, as such, the study of Earth Science is a valuable addition to a wide variety of scientific disciplines. Dartmouth offers majors in Earth Sciences and Environmental Earth Sciences. These programs are intended to provide a background in Earth Sciences sufficient for graduate work or employment in the field. Other majors (e.g., Physics, Chemistry, Economics, Engineering, Biology, etc...) may be modified with Earth Sciences to provide a more interdisciplinary course of study.
