The three correct answers describing the differences between solar wind and a geomagnetic storm are:
- Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
- Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
- Geomagnetic storms occur only occasionally; solar wind is constant.
These statements highlight how geomagnetic storms are transient events often linked to coronal mass ejections (CMEs), while solar wind is a continuous flow of charged particles from the sun.
