Question

which describes a difference between solar wind and a geomagnetic storm? select the three correct answers. (2 points)

• geomagnetic storms are associated with cmes; solar wind is associated with the constant activity in the sun.
• geomagnetic storms travel at the speed of light, while solar wind takes four days to reach earth.
• geomagnetic storms are constant; solar wind occurs only occasionally.
• solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
• geomagnetic storms occur only occasionally; solar wind is constant.

Explanation:

1. Coronal Mass Ejections (CMEs) trigger geomagnetic storms, while solar wind is a steady outflow from the Sun's corona.
2. Geomagnetic storms are driven by fast solar wind/CMEs (traveling faster than light speed is incorrect, but the key distinction of timing/trigger holds; the core difference here is the association with CMEs vs constant solar activity).
3. Solar wind is a constant stream, and intense solar wind events can cause geomagnetic storms, which are occasional, not constant.
4. Geomagnetic storms are occasional disturbances, while solar wind is a continuous phenomenon.

Answer:

A. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
D. Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
E. Geomagnetic storms occur only occasionally; solar wind is constant.
