Question
Inner core is made up of solid material because___________.
- There is no specific reason for this.
- Due to hotness of 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 most layer is in the center of the earth and bears the weight and pressure of the whole earth.
The correct answer is: The tremendous pressure from other layers is pushing the crust.
The correct option is d)The tremendous pressure from other layers is pushing the crust.
Unlike the outer core, the inner core is not liquid, it is not molten. The intense pressure in the inner core, the rest of the planet and all of its atmosphere, keeps the iron from melting. The pressure and density are too great for iron atoms to be in the liquid state.
