The Sun

The energy from the sun is created by a process called:

• nuclear fission
• nuclear fusion
• nuclear reaction
• nuclear core

Energy is created in the core when two _____________ atoms join together to form a ______________ atom.

• helium, hydrogen
• carbon, hydrogen
• nitrogen, helium
• hydrogen, helium

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

• photosphere
• chromosphere
• corona
• convection zone

What layer gives the sun it's reddish color during a solar eclipse?

• convection zone
• corona
• chromosphere
• photosphere

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

• chromosphere
• photosphere
• corona
• atmosphere

When prominences erupt into space releasing gas and energy we call this: 

• solar winds
• coronal outburst
• solar flares
• auroras

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
