Welcome to the Geosciences Department!

What is geoscience?


Geoscience is the study of the Earth and all of its systems. Interactions between the solid earth, the hydrosphere, atmosphere, and biosphere continually reshape the planet. Geoscientists investigate these interactions using interdisciplinary approaches to address questions related to how the Earth formed, how it evolved over geologic time, and how its continued evolution affects the environment in which we live.


What does geosciences look like at Wellesley?


At Wellesley, the Geosciences department offers a wide range of courses and research opportunities. Our courses examine earth, ocean, climate, and planetary processes and are often cross-listed with other STEM departments like Environmental Studies, Astronomy, and Chemistry. The research done by the faculty also demonstrate the interdisciplinary nature of the geosciences and involve systems ranging from EPA SuperFund sites to lake sediments to Antarctic glaciers to the rocks of New York City. Learn more about faculty research on the GEOS in the News page.
