Our students and geoscientists study the properties of minerals, rocks, soils, sediments and water, using multiple lenses -- stratigraphy, paleobiology, geochemistry, and planetary sciences. Their work informs our understanding of natural hazards such as earthquakes, volcanic eruptions, landslides, and floods. It helps us meet natural resource challenges through environmental and geological engineering, mapping and land use planning, surface and groundwater management, and the exploration and sustainable extraction of energy and minerals. It also helps us answer fundamental questions about the origin, history, and habitability of planets.
A sweeping analysis of marine fossils from most of the past half-billion years shows the usual rules of body size evolution change during mass extinctions and their recoveries. The discovery is an early step toward predicting how evolution will play out on the other side of the current extinction crisis.
