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.

Detailed explanation-2: -The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick! Crust: The Earth’s thinnest layer! Mantle: The Earth’s thickest layer! Inner Core: The hottest Earth layer!

Detailed explanation-3: -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-4: -Answer and Explanation: The Earth’s layers from coolest to hottest are: crust, mantle, outer core, and inner core.

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!!!!!!
