Electrically charged particles from space travelling at speeds of several hundred km/sec can severely harm living beings if they reach the surface of the Earth. What prevents them from reaching the surface of the Earth?
Detailed Explanation:
Earth's magnetic field (magnetosphere) acts as a protective shield, deflecting charged particles (solar wind, cosmic rays) toward the polar regions.
When these particles collide with atmospheric gases near the poles, they create auroras (Aurora Borealis and Aurora Australis), preventing direct surface exposure that would harm living organisms.
