Question

The thickness of the core is​

Answer 1

Explanation:

The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel. The NiFe alloy of the outer core is very hot, between 4,500° and 5,500° Celsius (8,132° and 9,932° Fahrenheit).

Answer 2

The Earth's core, unlike the yolk of an egg, is comprised of two separate parts:

• A liquid outer core that is 2,200 kilometers thick and a solid inner core that is 1,250 kilometers thick.
• The central layer, outer layer, middle, and shell are the four major layers that reach the earth. The central layer is the Earth's innermost layer, located at its core.
• It's mostly composed of nickel & iron, and despite being extremely heated, the inner core stays solid due to intense pressure.
