Overview

Model analysis suggests oxidation reactions in magma ocean unlikely to form water, indicating stability issues.

Key Points

  • Water formation from oxidation reactions is unlikely due to a water-poor atmosphere above the magma ocean.
  • The top boundary layer of the magma ocean is stable against convection due to the sinking of metallic iron.
  • Comprehensive modeling illuminates how hydrogen dissolution is not a significant factor in Earth's ocean formation.
  • This research supports a need for alternative hypotheses regarding the sources of Earth's water.
