4.
A large iceberg melts at the base, but not at the top, because of the reason that
ice at the base contains impurities which lowers its melting point.
due to the high pressure at the base, its melting point reduces.
the iceberg remains in a warmer condition at the base.

In general, melting point is directly proportional to pressure, but in case of water it is reversed.

@Dinesh.

We can say by Le Chatelier's principle on increasing the pressure the system will react in an way to minimize the effect (the volume decreases) so, generally substances tend to form solid but in case of water the as the liquid occupies less volume than solid the high pressure tends to form liquid (melting).
