THE SUN ASSESSMENT

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

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

• photosphere

• chromosphere

• corona

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

• chromosphere

• photosphere

• corona

The particles of the corona extend into space for millions of kilometers and spread 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:

• prominences

• sunspots

• solarspots

Most of the sun’s energy is a result of

• nuclear fusion  

• nuclear fission

• coronal mass ejection

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

• 1 000 year

• 100 000 years
