Inner Core Of The Earth : Recent Study
A recent study says that the inner core of Earth seems to have stopped spinning in the same direction as the rest of the planet.
- Inner core of the Earth is the innermost layer of the Earth.
- It is a solid metallic ball made mainly of iron.
- The inner core is solid due to the pressure caused by the weight put on it by the Earth’s other top layers.
- It is distinct from the outer core, which is a liquid.
- The inner core has an average radius of 1220 km.
- The boundary between the inner and outer cores is located at approximately 5150 km below the surface of the Earth.
- This boundary is called the Lehman Seismic Discontinuity
- Inner core temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC).
- It is predicted to have very high thermal and electrical conductivity.
- The inner core generates its own magnetic field and spins a bit faster than the rest of the planet.
