what is the composition of Earth's core

Answer 1

The Earth's core is believed to be composed primarily of iron (about 85%) and nickel (about 10%). Other elements such as sulfur, oxygen, and less abundant elements like gold and platinum may also be present in smaller amounts. The core is divided into two regions: the outer core and the inner core. The outer core is in a liquid state, while the inner core is believed to be solid due to the tremendous pressure at its center.
