Question

Why is the inner core a sold even though it has a higher temperature then the outer core which is a liquid

Answer 1

• Inner core is solid and outer core is liquid even though temperature of inner core is higher than outer temperature.

• It is because state of the body does not depend upon only temperature but also in pressure and melting point of materials.

Step-by-step explanation:

• Inner part of earth is called core. It has two parts outer core which has nickel-iron alloy and has radius 2100 km (according to NASA) inner core which has iron as the main element which has radius around 1220 km (according to NASA).

• Pressure of inner core is higher than outer core and as pressure increases the melting point of iron in inner core also increases.
