Question

If the temperature of the outer core is more than 5000C and outer core is in liquid
form, then the temperature of inner core must be more than the outer core but the
inner core is solid, why it is so​

Answer:

Explanation:

The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid.
