The study of Earth Sciences offers an integrated, interdisciplinary approach toward a better understanding of our planet. BU’s Department of Earth Sciences focuses on two broad areas: Climate/Surface Interactions and Tectonic/Lithospheric Processes. Faculty promote excellence in both teaching and research for students pursuing BA, MA, and PhD degrees, applying knowledge from chemistry, physics, ecology, biology, and mathematics to explore complex Earth processes. Their research provides historical perspective on crucial societal issues such as climate change, erosion, earthquakes, and fuel and water supply.
