Which describes a difference between solar wind and a geomagnetic storm? Select the three correct answers.

Question

A. Geomagnetic storms occur only occasionally; solar wind is constant.
B. Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.
C. Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
D. Geomagnetic storms are constant; solar wind occurs only occasionally.
E. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.

Answer 1

The three correct answers that describe a difference between solar wind and a geomagnetic storm are:

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

These options correctly distinguish between the ongoing nature of solar wind and the episodic nature of geomagnetic storms, as well as their respective causes and associations with solar activity.
