After the magnetosphere deflects most solar wind, what is the critical protective function of Earth's atmosphere regarding remaining radiation and particulate matter?
Answer
It absorbs the remaining radiation and particulate matter before it influences surface conditions
Earth utilizes a layered defense system against space weather hazards. The first layer is the magnetosphere, which deflects the bulk of the solar wind and charged particles. For the particles and radiation that manage to penetrate this magnetic shield, the atmosphere serves as the secondary, crucial barrier. The bulk of the atmosphere acts as an absorber, capturing and dissipating the remaining high-energy particles and radiation long before these elements could ever reach the surface or influence surface conditions such as wind speed or temperature.
