Effects of Geomagnetic storms
- The ionosphere gets heated and distorted, which makes long-range radio communication difficult.
- Ionospheric expansion can increase satellite drag, and it may become difficult to control their orbits.
- Geomagnetic storms disrupt satellite communication systems like GPS.
- Astronauts and high-altitude pilots would face high radiation levels.
- Electric power grids would see a high increase in voltage that would cause blackouts

Effects of Geomagnetic Storms:
Geomagnetic storms are disturbances in Earth's magnetosphere caused by solar activity, specifically by coronal mass ejections (CMEs) and high-speed solar winds. These storms can have various effects on our planet and its technological systems. The correct answer is option 'D', as all of the given effects are associated with geomagnetic storms.
1. Long-range radio communication becomes difficult due to radio wave distortion:
During geomagnetic storms, the ionosphere, which is responsible for reflecting radio waves back to Earth, becomes disturbed. As a result, the radio waves can be scattered or absorbed, leading to disruptions in long-range radio communication.
2. Satellite drag:
Geomagnetic storms can cause an increase in the density of the upper atmosphere, which leads to increased drag on satellites orbiting the Earth. This can result in the degradation of satellite orbits and a decrease in their operational lifetimes.
3. Astronauts and high-altitude pilots would face high radiation levels:
During geomagnetic storms, energetic particles from the Sun, such as protons and electrons, can penetrate the Earth's magnetosphere and reach the upper atmosphere. This increased radiation can pose health risks to astronauts on space missions and high-altitude pilots who are exposed to higher altitudes where the Earth's protective magnetic field is weaker.
4. Electric power grids would see a high increase in voltage that would cause blackouts:
Geomagnetic storms induce electrical currents in the Earth's crust and in long conductive structures such as power lines. These induced currents can cause disruptions in power grids, leading to voltage surges and potentially causing blackouts. Transformers and other electrical equipment can also be damaged due to these surges.
In summary, geomagnetic storms can have significant impacts on various aspects of human technology and infrastructure, including long-range radio communication, satellites, human health in space, and electric power grids. It is important for scientists and engineers to monitor and study these storms to better understand their effects and develop strategies to mitigate potential damages.
