Early Earth Habitability: Cosmic Inputs, the Solid Earth, and the Atmosphere

Session ID#: 29284

Session Description:
Constraining the bulk planetary evolution of Earth, and how this shaped early Earth’s surface environment, is crucial to ultimately understanding the timing and mechanism of the origin of life. The evolution of solid Earth, and thus also its surface, was greatly affected by factors such as bolide impacts, bulk planetary cooling, and the progressive mixture of materials from different reservoirs, among others. In this session, we seek contributions covering all aspects of the early Earth with the goal of better constraining conditions on a young planet and how this facilitated a nascent biosphere. Possible subjects include the GOE, the onset of plate tectonics, and the origin of life, etc. We especially invite contributions that highlight the often overlooked coupling of the surface and deep Earth to explain such milestones.
