Answer 1

The diameter of the core is 3,500 km.

The core is the innermost layer of the earth, primarily made of iron and nickel. It has a diameter of about 3,500 km and is the densest layer with a temperature around 5000°C. The core is divided into a molten outer core and a solid inner core due to pressure differences.
