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. Inner Core 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 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 the hottest layer. The temperature reduces as we move outward towards the crust.

Detailed explanation-4: -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-5: -The mantle is much hotter and has the ability to flow. The Outer and Inner Cores are hotter still with pressures so great that you would be squeezed into a ball smaller than a marble if you were able to go to the center of the Earth!!!!!!
