Question

Which describes a difference between solar wind and a geomagnetic storm? Select the three correct answers.(2 points)
Responses

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

Geomagnetic storms occur only occasionally; solar wind is constant.
Geomagnetic storms occur only occasionally; solar wind is constant.

Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
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 travel at the speed of light, while solar wind takes four days to reach Earth.

Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.

Answer 1

Responses

It forms radiation belts.
It forms radiation belts.

It generates auroras.
It generates auroras.

It develops solar wind.
It develops solar wind.

It causes geomagnetic storms.

Answer 2

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

1. **Geomagnetic storms occur only occasionally; solar wind is constant.**
2. **Geomagnetic storms are associated with CMEs (Coronal Mass Ejections); solar wind is associated with the constant activity in the sun.**
3. **Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.**

These responses highlight the differences in occurrence frequency, the causes of each phenomenon, and their relationship with each other.

Answer 3

The two correct answers that describe how solar weather affects Earth's magnetosphere are:

1. **It generates auroras.**
2. **It causes geomagnetic storms.**

These effects are due to the interaction of solar wind and coronal mass ejections with Earth’s magnetic field, leading to phenomena like auroras and geomagnetic storms.
