That depends on whether the ice is sea ice
(floating on the ocean), or land ice (sitting on
land). If it's land ice, then it doesn't
interact much directly, although if the land ice
melts then the resulting liquid water flows into
the ocean and raises the sea level because
there's now more water in the ocean.
The sea ice acts like any floating
object , except that it, too, can melt.
Archimedes' Law states that a floating
object displaces its weight , which means that
a melting iceberg will not raise sea level
because the amount of water that it will add to
the ocean exactly equals the amount of water that
it displaces by floating.
