What tells us that the inner core is made up of iron?

The inner core is believed to be made up of iron due to seismic studies which show that seismic waves travel faster in the inner core than in the outer core. This indicates that the inner core is likely solid, with iron being the most abundant and stable material at high pressure and temperature conditions found in the Earth's core. Additionally, experiments conducted in laboratories suggest that iron is capable of being solid at the extreme pressures and temperatures present in the inner core.


Is the inner core under extreme pressure?

Yes, the inner core of the Earth is under extreme pressure due to the weight of the Earth's layers above it. This pressure is what helps maintain the solid state of the inner core despite its high temperatures.


How does the inner core produce magnetic field?

The Earth's inner core is believed to generate the planet's magnetic field through a process called the geodynamo. This is where the rotation of the solid inner core against the liquid outer core creates electrical currents that, in turn, generate the magnetic field due to the conductive nature of the outer core material.


What direction does the inner core rotate?

The inner core of the Earth rotates in an eastward direction, which is the same direction as the Earth's overall rotation. This rotation is believed to be caused by the movement of the molten outer core surrounding it.


Why is the inner core solid but the outer core liquid if both regions have very high temperatures?

The inner core is solid because of the immense pressure at that depth, which keeps the iron and nickel in a solid state despite the high temperatures. In the outer core, where pressure is slightly lower, the higher temperatures cause the iron and nickel to be in a liquid state.
