Our Sun

How long does it take energy to pass through the radiation zone?

• 12 minutes
• 100 year
• 10,000 years
• 100,000 years

In which area of the sun does gas rise as it heats up, then fall back down as it cools?

• the core

• the radiative zone

• the convective zone

• the corona

When we look at the sun, what layer are we viewing?

• photosphere
• chromosphere
• corona
• convection zone

What layer of the sun's atmosphere gives the sun its "white halo" during a solar eclipse?

• chromosphere
• photosphere
• corona
• atmosphere

The particles of the corona extends into space for millions of kilometers and spreads into streams of electrically charged particles called:

• coronal discharge
• solar flares
• coronal ejection
• solar winds

Areas of gas on the sun's surface that are cooler than gases around them are called:

• corona
• prominences
• sunspots
• solarspots

Huge loops of reddish gas that connect sunspots are called:

• prominences
• solar flares
• coronal loops
• solar wind

Most of the sun’s energy is a result of

• nuclear fusion  
• nuclear fission
• atomic reactions
• coronal mass ejection
