1Heioseismology is the study of:
- AEarthquakes
- BSolar tremors
- CThe shaking of your car when your speakers are at max
2The tachocline is:
- AThe visible surface of the Sun.
- BThe boundary between the chromosphere and the corona
- CThe boundary between the radiative and convective zones.
3The tachocline is at:
- A0.4 R☼
- B0.7 R☼
- C10 R☼
4One of the results of helioseismology is that the Sun rotates as a solid body below the tachocline and as a fluid above it.
- ATrue
- BFalse
5Another result of helioseismology is that the Sun rotates:
- AFaster at the equator than at the poles.
- BSlower at the equator than at the poles.
- CThe Sun does not rotate.
6Another result of helioseismology is that there are currents on the Sun flowing:
- AFrom the equator to the poles on the surface.
- BFrom the poles to the equator at the tachocline.
- CBoth of the above.
7Sunspots are darker regions of the Sun’s surface that are:
- AAbout 1000 K cooler than the adjacent regions of the photosphere
- BAbout 1000 K hotter than the adjacent regions of the photosphere
8Sunspots are:
- ADarker regions of the Sun’s surface
- BAbout 1000 K cooler than the adjacent regions of the photosphere
- CRegions of strong magnetic fields that suppress light emission
- DAll of the above
9The solar cycle is:
- AThe variation of the solar output
- BIs about 11 years long
- CConsists of a solar minimum and a solar maximum
- DAll of the above
10We now think that the length of the solar cycle is determined by:
- AThe variation of the solar output
- BThe meridional circulation
- CBubbling on the surface.
11At solar maximum, the solar magnetic field reverses.
- ATrue
- BFalse
12At solar maximum we have more:
- ASolar output
- BSunspots
- CFlares
- DProminences
- ECMEs
- FLoops in the magnetic carpet
- GAll of the above
13The sunspot number is used to track:
- ASolar activity (the solar cycle)
- BThe proton-proton cycle
- CThe music of the spheres
14The solar magnetic field has a:
- APoloidal component
- BToroidal component
- CBoth of the above
15The solar dynamo is the source of:
- AFusion on the Sun
- BThe Sun’s global magnetic field
- CPressure in the Sun
16The solar dynamo resides:
- AIn the transition region
- BIn the photosphere
- CAt the tachocline
17The solar dynamo consists of :
- AThe winding up of the polar field into a toroidal field
- BThe break up of the toroidal field due to convection
- CThe break up of the toroidal field due to meridional circulation
- DAll of the above
