The fraction of Earth covered by water has changed significantly over geological history
the verdict
SUPPORTED
the evidence backs this
confidence 81/100
Geological and paleoclimatic records demonstrate that the fraction of Earth covered by water has varied considerably throughout history due to glacial cycles, tectonic movements, and eustatic sea-level shifts.
