1 answer
The composition of Earth's core is primarily made up of iron, with smaller amounts of nickel, sulfur, and lighter elements like oxygen and silicon. It is believed to be in a molten or liquid state due to the intense heat and pressure. The outer core is predominantly liquid, while the inner core is solid. The core is also very dense, with an average density of about 13 g/cm³.
