GENERAL KNOWLEDGE

Detailed explanation-1: -Temperature in the inner core is about 5, 200° Celsius (9, 392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm). The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten.

Detailed explanation-2: -The inner core is a solid area made mostly of iron and a smaller amount of nickel. It acts as a giant furnace, with temperatures around 5, 000-6, 000 degrees Celsius. This heat causes the outer core to melt and turn into liquid magma.

Detailed explanation-3: -The temperature at the inner core’s surface is approximately 5, 700 K (5, 430 °C) or 9806 °F, which is about the temperature at the surface of the Sun.
