Geomagnetic storms are constant; solar wind occurs only occasionally.
Geomagnetic storms are constant; solar wind occurs only occasionally.

Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.

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.

Answer 1

To identify the differences between solar wind and geomagnetic storms, the following statements are correct:

1. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun. - This statement is accurate because geomagnetic storms are often triggered by coronal mass ejections (CMEs), whereas solar wind is a continuous stream of charged particles released from the sun.

2. Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind. - This is correct as well, indicating that solar wind can lead to geomagnetic storms, but geomagnetic storms themselves are not a source of solar wind.

3. Geomagnetic storms occur only occasionally; solar wind is constant. - This statement is also true, as solar wind is a continuous phenomenon, whereas geomagnetic storms are intermittent events triggered by specific solar activity.

So the three correct choices 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.
