Which set of terms describes a realistic cause-effect relationship between solar weather and Earth's magnetosphere? Select the two correct answers.

A: geomagnetic storm -- aurora

B: coronal mass ejection -- geomagnetic storm

C: solar wind -- interplanetary magnetic field

D: radiation belt -- aurora

A: geomagnetic storm -- aurora

B: coronal mass ejection -- geomagnetic storm

Explanation:

A cause-effect relationship is one in which there is an underlying trigger for some observations. Here, the cause we are considering is the solar weather. Effect is on the earth's magnetosphere.

Solar weather are the spectacular effects of the sun. Some of these are the production of geomagnetic storm and coronal mass ejection.

A geomagnetic storm is a temporary event leading to the formation of Auroras. In this scenario, magnetic fields and solar winds from the sun interacts with the magnetosphere causing a geomagnetic storm which leaves trails of beautiful light in the sky.

A full blown geomagnetic storm results from coronal mass ejection by the sun. This is a massive release of plasma from the sun's corona region. These energized particles leads to a geomagnetic storm or solar storm as they interact with the earth's magnetosphere.
