Here are ten facts about Earth's core:

1. Earth's core is divided into a solid inner core and a liquid outer core.

2. The Here are the remaining eight fact

3. The inner core is a solid iron-nickel alloy with a temperature of around 5,000 to 6,000°C.

4. The outer core is a liquid iron-nickel alloy with a temperature of around 4,000 to 6,000°C.

5. The core accounts for about 1/6 of the Earth's total volume.

6. The core is estimated to be around 6,371 km (3,959 miles) away from the Earth's surface.

7. The Earth's core is responsible for generating the planet's magnetic field.

8. The liquid outer core is responsible for the Earth's geodynamo effect, which creates the Earth's magnetic field.

9. The core is under immense pressure, with estimates suggesting it's around 3.5 million times greater than the pressure at the Earth's surface.

10. Scientists believe the Earth's core is around 4.5 billion years old, and is thought to be one of the oldest parts of the planet.
