Which describes a difference between solar wind and a geomagnetic storm? Select the three correct answers.(2 points)
Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
Geomagnetic storms occur only occasionally; solar wind is constant.
Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.
Geomagnetic storms are constant; solar wind occurs only occasionally.
Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
The correct answers are:
1. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
2. Geomagnetic storms occur only occasionally; solar wind is constant.
3. Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
How does solar weather affect Earth's magnetosphere? Select the two correct answers.(1 point)
It causes geomagnetic storms.
It develops solar wind.
It forms radiation belts.
It generates auroras.
The correct answers are:
1. It causes geomagnetic storms.
2. It generates auroras.
The three correct answers are:
1. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
2. Geomagnetic storms occur only occasionally; solar wind is constant.
3. Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.
The correct answers are:
1. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
2. Geomagnetic storms occur only occasionally; solar wind is constant.
3. Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.
To determine these answers, you need to understand the differences between solar wind and geomagnetic storms.
1. Geomagnetic storms are associated with coronal mass ejections (CMEs). CMEs are massive eruptions of plasma and magnetic fields from the sun. Geomagnetic storms occur when these CMEs interact with the Earth's magnetic field, causing disturbances in the magnetosphere. On the other hand, solar wind is a continuous stream of charged particles (mostly electrons and protons) emitted by the sun's corona. It is a result of the constant activity of the sun and is not directly associated with CMEs.
2. Geomagnetic storms occur only occasionally, whereas solar wind is constant. Geomagnetic storms are more intermittent events that happen when the Earth's magnetosphere is significantly disturbed, usually by strong solar activity. Solar wind, on the other hand, is continuously blowing from the sun, even during periods of low solar activity.
3. Geomagnetic storms do not travel at the speed of light; instead, they take some time to reach Earth. Solar wind, on the other hand, takes about four days to travel from the sun to Earth. Geomagnetic storms are caused by disturbances in the magnetosphere due to the interaction with CMEs, and the time it takes for these disturbances to reach the Earth depends on the speed of the associated CME. Solar wind travels at a slower speed compared to the speed of light.
Therefore, the correct answers are:
- Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.
- Geomagnetic storms occur only occasionally; solar wind is constant.
- Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.
