Although the search for liquid water on mars is ongoing, scientists have known for quite some time that mars has water ice at its poles, even though volcanic activity has never been observed on mars. does this finding prevent the inside-out model from becoming a theory? why or why not?
yes, because mars is near earth and was likely affected by the same comets.
yes, because it shows that volcanic activity is not necessary for a planet to have water.
no, because data taken on mars is not applicable to ocean formation theory on earth.
no, because a single observation on one planet is not sufficient to discredit a theory.
