Detailed explanation-1: -Inner Core The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1, 220 kilometers (758 miles). Temperature in the inner core is about 5, 200° Celsius (9, 392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).
Detailed explanation-2: -The inner core is the hottest part of our planet, at temperatures between 9, 000 and 13, 000 degrees Fahrenheit (5, 000 and 7, 000 degrees Celsius).
Detailed explanation-3: -The inner core is made up of the same metals as the outer core (iron and nickel) but, instead of being liquid, it is a solid. The inner core reaches temperatures of up to 5, 500°C. With its immense heat energy, the inner core is like the engine room of the Earth.
Detailed explanation-4: -The Upper Mantle is much stronger than the asthenosphere at about 500-900°C, and the Lower Mantle is denser and hotter, reaching temperatures over 4, 000°C.
