1. Outer Core:

* Composed primarily of liquid iron (about 88%) and nickel (about 5.5%).

* Also contains small amounts of sulfur, silicon, and oxygen.

* Extremely hot, with temperatures estimated to be between 4,500°C and 5,500°C (8,132°F and 9,932°F).

* The liquid iron is constantly moving, creating electric currents that generate Earth's magnetic field.

2. Inner Core:

* Composed primarily of solid iron and nickel, with trace amounts of other elements.

* Extremely dense, with a pressure estimated to be over 3.5 million times that at Earth's surface.

* Despite the high temperature (around 5,200°C or 9,392°F), the intense pressure prevents the iron from melting.

Interesting Facts:

* The core is about 1,220 kilometers (758 miles) thick.

* The inner core is about 1,220 kilometers (758 miles) in radius.

* The core makes up about 31% of the Earth's total mass.
