- What happened: Earth’s magma ocean cooled; volcanic outgassing plus comet/asteroid delivery produced water vapor that condensed and pooled in crustal basins to form the first oceans.
- Which plates: no modern named plates—only proto‑plates/juvenile lithospheric blocks and nascent subduction zones; early microplate motions gradually birthed plate tectonics.
- How it changed the surface: formed a stable hydrosphere that drove chemical weathering, sedimentation, crust stabilization and continental growth, reshaping topography and enabling life.
