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?
[UPSC Civil Services Exam – 2012 Prelims]
(a) The Earth’s magnetic field diverts them toward its poles
(b) Ozone layer around the Earth reflects them back to outer space
(c) Moister in the upper layers of atmosphere prevents them from reaching the surface of the Earth
(d) None of the statements (a),(b) and (c) is correct.
- High-speed electrically charged particles from space can cause serious harm to living beings upon reaching the Earth’s surface.
- However, the Earth’s magnetic field steers these particles towards its poles.
