Earth History

Throughout the 4.6 billion year history of Earth, change has been the norm. Earth scientists who study the history of the planet reconstruct past landscapes, ecosystems, and environments, including in the oceans and on land. Historians of the Earth investigate the major physical and biological events of the geologic past, with a major focus on evidence for ancient life and how, why, and when it has changed through time.
