The geological record holds clues about how life, climate, and Earth's interior have evolved together. Princeton researchers investigate Earth's primordial magnetic field, continental drift, the formation and transformation of Earth's outer shell, disruptions in carbon cycling, fossil evidence of biological evolution and catastrophic die-offs, and past climate shifts.
Princeton's Geosciences Department, along with its cross-disciplinary programs and research centers, acts as the university's hub for studying Earth systems, atmospheric phenomena, ocean dynamics, and environmental science. This brings together diverse scientific perspectives and research efforts aimed at comprehending Earth's internal structure, climate patterns, living systems, air and water environments, surface features, and their complex interactions across geological time.
