inner core

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: -Answer and Explanation: The Earth’s layers from coolest to hottest are: crust, mantle, outer core, and inner core. The crust’s temperature can vary from the air temperature on top of the crust to 1600 degree Fahrenheit.
