During each ice age, a significant portion of the Earth's water is trapped
on the northern continents, enough to lower sea level just a bit.
Shorelines move outward, and the Berring "Straight" becomes dry land.  This
is how humanity first came to the Americas.  During each interglacial,
the ice melts and the sea level rises.  Evidence of this includes phenomenon
like fjords (valleys carved by glaciers, now filled with sea water) and
estuaries (much the same thing, only a river valley is invaded by the sea).
These features would not have formed while the sea was at its present
level.  I'm sure a geologist could give better examples.
