Responses
They are caused by outward fluctuations of the sun's magnetic field.
They are caused by outward fluctuations of the sun's magnetic field.
They appear as dark spots on the sun's surface.
They appear as dark spots on the sun's surface.
They tend to occur during active periods of the solar cycle.
They tend to occur during active periods of the solar cycle.
They appear as bright spots on the sun's surface.
They appear as bright spots on the sun's surface.
The two correct responses are:
- They are caused by outward fluctuations of the sun's magnetic field.
- They tend to occur during active periods of the solar cycle.

Responses
uniform clockwise rotation of charged particles
uniform clockwise rotation of charged particles
uneven churning of plasma
uneven churning of plasma
upward movement of super-heated gases in the convective zone
upward movement of super-heated gases in the convective zone
rapid spinning of metals in the core
rapid spinning of metals in the core
The cause of the sun's magnetic properties is the uneven churning of plasma.
The two correct responses are:
1. They are caused by outward fluctuations of the sun's magnetic field.
2. They tend to occur during active periods of the solar cycle.
The characteristic that is shared by sunspots, solar flares, and coronal mass ejections are:
1. They are caused by outward fluctuations of the sun's magnetic field.
2. They tend to occur during active periods of the solar cycle.
To arrive at the correct response, we can analyze each option:
- "They are caused by outward fluctuations of the sun's magnetic field." This option is correct because all three phenomena - sunspots, solar flares, and coronal mass ejections - are indeed caused by outward fluctuations of the sun's magnetic field.
- "They appear as dark spots on the sun's surface." This option is only partially correct. While sunspots do appear as dark spots on the sun's surface, solar flares and coronal mass ejections do not have this characteristic.
- "They tend to occur during active periods of the solar cycle." This option is correct because all three phenomena tend to occur more frequently during active periods of the solar cycle.
- "They appear as bright spots on the sun's surface." This option is not correct. Sunspots appear as dark spots on the sun's surface, while solar flares and coronal mass ejections do not appear as bright spots.
Therefore, the correct responses are:
1. They are caused by outward fluctuations of the sun's magnetic field.
3. They tend to occur during active periods of the solar cycle.
