The outer core, one of the three layers of the Earth, is approximately 1,430 miles (2,300 kilometers) thick and between 7,200 and 9,000 F. According to National Geographic, the outer core is mostly composed of iron and nickel in a liquid alloy form. National Geographic reports that the temperature of the Earth’s outer core is estimated to be between 7,200 and 9,000 degrees Fahrenheit. At its outer edge, where it meets the atmosphere, the crust’s temperature is the same temperature as that of the air.

The inner core is the fourth layer inside the Earth. This is the depth and temperature of the Earth's layers: Inner Core, Outer Core, Mantle, and Crust. Continental lithosphere is the thickest in the world. The NiFe alloy of the outer core is very hot, between 4,500° and 5,500° Celsius (8,132° and 9,932° Fahrenheit). The inner core has an estimated radius of 1,220 km, while the outer core extends beyond it to a radius of about 3,400 km. Although the inner core is very hot, it is not liquid like the outer core. The outer core of the Earth is a liquid layer about 2,260 kilometers thick. Due to this high temperature, the outer core is liquid despite being made up of iron and nickel. Its temperature ranges from 2,200 to 5,000 degrees Celsius, and it is about 2,200 km thick.

The temperature of the outer core is 4,000 to 8,000 K. The hottest region of this core of the earth is about 3,730-7,730 degrees Celsius or 6,740-13,940 degrees Fahrenheit.

Outer core. Beneath the ocean the lithosphere is thinner, extending down only about 100 kilometers (60 miles). As the Earth spins, the outer … The outer core is not under enough pressure to be solid, so it … Because of these high temperatures, the metals in the outer core are melted. However, once more, from the ab initio simulation of the free energy of the pure iron liquid, we can obtain first-order estimates for a range of thermodynamic properties at the conditions of the Earth’s outer core. Because of these high temperatures, the metals in the outer core are melted. It has a radius of about 2,300 kilometers or 1,400 miles thick. The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel. The temperature of the inner core is estimated to be about 5,400 degrees C or 9,800 degrees F, far beyond iron’s melting point. How Do We Know About the Outer Core? The earth’s inner core is a solid ball of iron, nickel and other metals, while the outer core is liquid metal composed of iron and nickel as well. This image shows the spinning core. The higher pressure makes it solid even though the temperatures of the inner core and outer core are basically the same. The outer core is located around 1800 miles under the crust and approximately 1400 miles thick.

It has a solid inner core and a liquid outer core.. Unlike the inner core, the outer core is liquid. The transition between the inner core and outer core is located approximately 5,150 km beneath the Earth's surface.

The outer core has temperatures ranging from 4,000 degrees C to 6,100 degrees C (7,232 oF to 11,000 oF).
