radiation belt -- aurora
geomagnetic storm -- aurora
geomagnetic storm -- aurora
solar wind -- interplanetary magnetic field
solar wind -- interplanetary magnetic field
coronal mass ejection -- geomagnetic storm
solar wind -- interplanetary magnetic field

When is the possibility of solar weather affecting terrestrial weather the highest?(1 point)
during solar minimum
during solar minimum
during the solar cycle
during the solar cycle
during solar maximum
during solar maximum
during Total Solar Irradiance
during solar maximum
The two correct answers are:
1. Geomagnetic storm -- aurora: Geomagnetic storms are caused by disturbances in Earth's magnetosphere, which can result in the appearance of auroras in the atmosphere.
2. Coronal mass ejection -- geomagnetic storm: Coronal mass ejections (CMEs) are large releases of plasma and magnetic field from the Sun's corona. When a CME interacts with Earth's magnetosphere, it can cause a geomagnetic storm.
The two correct answers that describe a realistic cause-effect relationship between solar weather and Earth's magnetosphere are:
1. Geomagnetic storm -- aurora: A geomagnetic storm is a disturbance in Earth's magnetosphere caused by the interaction between the Earth and the solar wind. During a geomagnetic storm, charged particles from the solar wind can enter Earth's magnetosphere and cause the phenomenon known as an aurora, where charged particles in the atmosphere emit light and create colorful light displays.
2. Solar wind -- interplanetary magnetic field: The solar wind is a stream of charged particles emitted by the Sun. As the solar wind reaches Earth, it carries with it an interplanetary magnetic field. This magnetic field can interact with Earth's magnetosphere, causing various effects such as disturbances in the magnetosphere and the creation of auroras.
To determine which answer options describe a realistic cause-effect relationship between solar weather and Earth's magnetosphere, it is essential to understand the concepts involved. In this case, knowing that geomagnetic storms are caused by interactions between Earth and the solar wind and that the solar wind carries an interplanetary magnetic field can help identify the correct choices.
