Detailed explanation-1: -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).

Detailed explanation-2: -Outer Core: The outer core, which is liquid, is about 1300 miles (2092 km) thick. Both the inner and outer cores consist primarily of iron and nickel and are extremely hot with temperatures ranging from 7200–9000℉ (4000–5000℃).

Detailed explanation-3: -The core is the centre of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron and molten rock.

Detailed explanation-4: -The outer core is located about 1800 milesbeneath the crust and is about 1400 miles thick. The outer core is composed of the melted metals nickel and iron.

Detailed explanation-5: -Inner Core Composition and Formation The solid spheroid that comprises the inner core of the Earth is made of different metals, specifically, mostly iron and nickel. Siderophiles, or elements that dissolve in iron, are also found in the inner core.
