Answer 2

The inner core of the earth is rich in iron and nickel​

• The inner core of the Earth is rich in Iron and Nickel. But in that area, the pressure is so high that it is found in solid form.
• The temperature of the inner core of the Earth is almost the same as the surface of the sun is about 5505 degrees Celsius.
• Every year the inner core of the earth increases by 1 mm. The inner core is the fourth layer inside the earth.
• It has a radius of 1220 KM which is about 20% of the earth's radius or we can save 70% of the moon's radius
