Detailed explanation-1: -The churning metal of the outer core creates and sustains Earth’s magnetic field. The hottest part of the core is actually the Bullen discontinuity, where temperatures reach 6, 000° Celsius (10, 800° Fahrenheit)-as hot as the surface of the sun.
Detailed explanation-2: -The interior of Earth is very hot (the temperature of the core reaches more than 5, 000 degrees Celsius) for two main reasons: The heat from when the planet formed, The heat from the decay of radioactive elements.
Detailed explanation-3: -The inner core is hotter than the outer core. However, in the outer core, the heat melts the core despite the amount of pressure present. In the case of the inner core, the effect of the pressure trumps the effect of heat and holds the core’s particles close together to form a tough solid.
