Many grade school teachers don't know squat about science, I once got an
email from a concerned parent because her son's teacher was telling
the students that the grand canyon was formed by a meteorite, as
opposed to the less obvious river....
However, if scientist can figure out the rate of uplift of the the mountain
they can plot the sea level at that point in history. That sea level could
have been higher then the modern. So maybe the teachers portrayed an
incorrect analysis of what was going on, if they read that sea level there was
higher than modern or something. I refer you to fig2 on that factsheet(sorry
i keep bringing it up, it's the reference i know best) http://pubs.usgs.gov/factsheet/fs2-00/
