A large iceberg melts at the base, but not at the top, because of the reason that Correct Answer Due to the high pressure at the base, its melting point reduces

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).
