Question

Give reasons The inner core is solid though it is hotter than the liquid outer core.​

Answer 1

Answer:

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.

Answer 2

➤ Answer :-

• As we go deeper to the interior of earth,the temperature starts increasing.
• This same happens here the inner core extends from 5150km to depth 6371 km(earths centre).
• As the materials in this layer are under extreme pressure, the inner core is in solid state.the temperature here is almost equal to the surface of the sun
