GENERAL GEOLOGY

Detailed explanation-1: -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. The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1, 220 kilometers (758 miles).

Detailed explanation-2: -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.

Detailed explanation-3: -The Inner Core It is the centre and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel with temperatures up to 5, 500oC. Due to its immense heat energy, the inner core is more like the engine room of the Earth.

Detailed explanation-4: -That led to the conclusion that the temperature of the center of the Earth is about 6000 degrees Celsius-a temperature about 9% higher than what exists on the surface of the Sun.

Detailed explanation-5: -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.
