    Question

    Inner core is made up of solid material because

    1. There is no specific reason for this.
    2. It is due to the hotness of the core, it (core) turns from solid to liquid.
    3. Weight of the crust is pushing down the core.
    4. The tremendous pressure from other layers is pushing the crust.

    hintHint:

    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.
