Earth's core is the innermost layer of the planet, primarily composed of iron and nickel, and is divided into a solid inner core and a liquid outer core. The movement of the liquid outer core generates Earth's magnetic field, which is crucial for maintaining the planet's atmosphere and protecting it from solar radiation.

Earth's magnetic field is a geomagnetic phenomenon generated by the movement of molten iron within its outer core, creating a protective shield that deflects solar wind and cosmic radiation. This field is crucial for navigation, wildlife migration, and maintaining the planet's atmosphere against solar erosion.
