Inner core is made up of solid material because
- There is no specific reason for this.
- It is due to the hotness of the core, it (core) turns from solid to liquid.
- Weight of the crust is pushing down the core.
- The tremendous pressure from other layers is pushing the crust.
Hint:
The inner core is solid the pressure from all the surrounding layers is driven to the inner core.
The correct answer is: The tremendous pressure from other layers is pushing the crust.
- The inner core is the innermost layer of the earth.
- It has three layers surrounding it the outer core, the mantle, and the crust.
- The pressure from all three surrounding layers is received by the inner core.
- So it is solid.
