Explanation:
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: -The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to that of the inner core.
Detailed explanation-3: -The core–mantle boundary (CMB) is the interface between the solid rocky silicate mantle and liquid iron alloy outer core.
