The correct answers are:
- It generates auroras.
- It causes geomagnetic storms.
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.
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.
Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.
The two correct answers are:
1. It generates auroras.
2. It causes geomagnetic storms.
To determine how solar weather affects Earth's magnetosphere, we need to understand the two correct answers from the given options.
1. It generates auroras: When the solar wind from the Sun reaches Earth, it interacts with the magnetic field of the Earth. This interaction causes charged particles to enter the atmosphere near the poles, resulting in the beautiful glow known as the aurora borealis (northern lights) in the northern hemisphere and the aurora australis (southern lights) in the southern hemisphere.
2. It causes geomagnetic storms: Solar activity, such as solar flares or coronal mass ejections, can release a large amount of energy. These energetic outbursts can impact Earth's magnetosphere, causing disturbances in the Earth's magnetic field. These disturbances are known as geomagnetic storms. Geomagnetic storms can lead to a variety of effects, such as power grid fluctuations, satellite communication disruptions, and disruptions in navigation systems.
Therefore, the correct answers are:
- It generates auroras.
- It causes geomagnetic storms.
