How does the inner core affect all of the earth's other layers

The inner core of Earth, owing to its composition and orientation, affects the Earth in a number of ways.

Explanation:

The inner core of Earth is mainly constituted of solid iron. It makes up 33% of the total mass of Earth, giving the Earth the required balance and stability to rotate around itself and to revolve around the sun. The magnetic field properties that the Earth possesses are due to its solid iron core. The tremendous heat in the inner core of the Earth keeps the outer core in the liquid state. In this way, it keeps the possibility of generation of the convection currents alive.
