Both Earth and the planet Venus have a large amount of water vapor in the atmosphere, and have extensive volcanic activity throu
ghout history. Does this observation support or disprove the inside-out model? Supports, because Venus is near Earth and would have been hit by all the same comets.
Disproves, because a single observation can discredit a theory.
Disproves, because data taken on Venus is not applicable to Earth.
Supports, because it shows that volcanic activity may be related to water vapor.
