Answer 1:
The melting point of any substance depends on
Temperature and on PRESSURE. So, the molten outer
core at about 5000 Kelvin degrees of temperature
is at a low enough pressure; this makes the iron
of the core to be in liquid state. But because
the Temperature of the inner core is almost the
same, BUT THE PRESSURE is larger, then the inner
core can be solid.
