Which component helps shield Earth's atmosphere from solar wind?

Explanation:
Earth's magnetic field acts as a global shield, creating a magnetosphere that deflects charged particles from the Sun. The solar wind would otherwise gradually strip away atmospheric gases and expose the surface to more radiation, so this magnetic barrier is crucial for preserving the atmosphere. The ozone layer handles ultraviolet radiation, not charged particles from the solar wind, while the hydrosphere and albedo relate to water and reflectivity rather than shielding from solar wind. In short, the magnetic field is the component that protects Earth’s atmosphere from solar wind.
