The two correct answers that describe a realistic cause-effect relationship between solar weather and Earth's magnetosphere are:
- geomagnetic storm -- aurora
- coronal mass ejection -- geomagnetic storm
These relationships illustrate how solar activity can impact Earth's magnetosphere and lead to phenomena like auroras. Geomagnetic storms, which can be caused by coronal mass ejections, can produce auroras as a visible effect of the interaction between solar wind and Earth's magnetic field.
