What characteristic is shared by sunspots, solar flares, and coronal mass ejections? Select the two correct responses.(1 point)
Responses
They tend to occur during active periods of the solar cycle.
They are caused by outward fluctuations of the sun's magnetic field.
They appear as bright spots on the sun's surface.
They appear as dark spots on the sun's surface.
The correct responses are:
- They tend to occur during active periods of the solar cycle.
- They are caused by outward fluctuations of the sun's magnetic field.
To determine the characteristics shared by sunspots, solar flares, and coronal mass ejections, we can examine each response and see which are correct.
1. They tend to occur during active periods of the solar cycle.
This statement is correct. Sunspots, solar flares, and coronal mass ejections are all more likely to occur during periods of increased solar activity, which is associated with the solar cycle.
2. They are caused by outward fluctuations of the sun's magnetic field.
This statement is correct. Sunspots, solar flares, and coronal mass ejections all involve variations and disturbances in the sun's magnetic field, which can result in these phenomena.
3. They appear as bright spots on the sun's surface.
This statement is incorrect. Sunspots actually appear as dark spots on the sun's surface. Solar flares and coronal mass ejections are not visible as distinct spots on the Sun, but rather as intense bursts of radiation or matter released from the Sun.
4. They appear as dark spots on the sun's surface.
This statement is correct. Sunspots are dark areas on the Sun's surface, characterized by cooler temperatures compared to the surrounding regions.
Therefore, the two correct responses that correctly describe characteristics shared by sunspots, solar flares, and coronal mass ejections are:
- They tend to occur during active periods of the solar cycle.
- They are caused by outward fluctuations of the sun's magnetic field.
The two correct responses are:
1. They tend to occur during active periods of the solar cycle.
2. They are caused by outward fluctuations of the sun's magnetic field.
