Which phenomenon causes geomagnetic storms on Earth?

1. Ocean currents
2. Solar flares and coronal mass ejections
3. Earth’s rotation
4. Lunar eclipses

Correct answer: Solar flares and coronal mass ejections

Solution

Geomagnetic storms are caused by intense solar activity, especially solar flares and coronal mass ejections, which send charged particles toward Earth. When these interact with Earth’s magnetosphere, they disturb the magnetic field and create storms.
