- GPS and navigation systems could fail.
- Tsunamis could occur at equatorial regions.
- Power grids could be damaged.
- Intense auroras could occur over much of the Earth.
- Forest fires could take place over much of the planet.
- Orbits of the satellites could be disturbed.
- Shortwave radio communication of the aircraft flying over polar regions could be interrupted.
Select the correct answer using the code given below:
(a) 1, 2, 4 and 5 only
(b) 2, 3, 5, 6 and 7 only
(c) 1,3, 4, 6 and 7 only
(d) 1, 2, 3, 4, 5, 6 and 7
The correct answer is (c) 1, 3, 4, 6, and 7 only. Here’s an explanation for each option:
- GPS and navigation systems could fail: Solar storms can cause disruptions to GPS satellites and affect navigation systems. Mild solar storms can cause more serious problems to GPS satellites than once-in-a-century events.
- Tsunamis could occur at equatorial regions: Solar storms cannot directly cause tsunamis on Earth. However, some researchers argue that solar storms may indirectly lead to tsunamis on Earth.
- Power grids could be damaged: Solar storms can damage power grids, causing widespread blackouts. For example, the 1989 Quebec blackout was caused by a solar storm.
- Intense auroras could occur over much of the Earth: Solar storms can lead to auroras closer to the equator than is possible during calm conditions. copyright©iasexpress.net
- Forest fires could take place over much of the planet: There is no direct evidence linking solar storms to widespread forest fires.
- Orbits of the satellites could be disturbed: Solar storms can damage satellites in orbit around Earth by inducing currents that can burn out their circuit boards.
- Shortwave radio communication of the aircraft flying over polar regions could be interrupted: Solar storms can disrupt high-frequency communication systems such as ground-to-air, shortwave, and ship-to-shore radio.
- Solar storms are caused by solar flares and coronal mass ejections (CMEs) from the Sun.
- Geomagnetic storms occur when the solar flares and CMEs interact with Earth’s electromagnetic field.
- Solar storms are divided into 5 classes (G-1 to G-5) based on their impact, with G-5 being the most severe.
- Solar storms can cause beautiful phenomena known as auroras or Northern Lights.
- The Carrington Event of 1859 was a massive geomagnetic storm caused by a solar flare and CME.
- Solar storms can also disrupt internet service providers and telecommunication networks on Earth.
