The core is the central part of something, often considered the most important or essential part. In science, the term "core" is commonly used to refer to the central region of a planet or celestial body.

Earth's Core

Earth's core is divided into two main parts: the outer core and the inner core. The outer core is a liquid layer made up of iron and nickel, while the inner core is a solid ball of iron and nickel. The core plays a crucial role in generating Earth's magnetic field.
