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: -Right now, the Earth’s core is not entirely molten. The inner core is a sphere of solid iron, while the outer core is made of molten iron thousands of kilometres thick.
Detailed explanation-3: -The outer core is a liquid molten (liquid) rock. Layer 3. The mantle is dense and mostly solid rock.
Detailed explanation-4: -The outer core is composed of the melted metals nickel and iron.
Detailed explanation-5: -The outer core is made of iron and nickel with some oxygen and sulfur. It is so hot that they melt into liquid. Because Earth is constantly spinning around, the liquids in the outer core move and flow like ocean currents.
