What is the depth of the outer core in KM?

Geology

about 2,400 km2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth’s solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth’s surface.

What is the depth of the inner core in KM?

The temperatures in the inner core are as hot as the surface of the sun, about 5505 °C. Earth’s inner core is 1,230 to 1,530 km thick.

What is the starting depth of the outer core in KM?

The Inner and Outer Core

Inner Core Outer Core
solid liquid
made of solid metals made of liquid metals
temperature as high as 9,000° F (4,982° C) temperatures range from 4,000 to 9,000° F (2,204 to 4,982° C)
depth: about 3,200 to 3,900 miles (5,150 to 6,276 km) depth: about 1,800 to 3,200 miles (2,897 to 5,150 km)

How thick is the outer core of the Earth in km?

2,200 km-

Unlike the yolk of an egg, however, the Earth’s core is actually made up of two distinct parts: a 2,200 km-thick liquid outer core and a 1,250 km-thick solid inner core.

How deep below the surface is the outer core?

The outer core begins approximately 2,889 km (1,795 mi) beneath Earth’s surface at the core-mantle boundary and ends 5,150 km (3,200 mi) beneath Earth’s surface at the inner core boundary.
