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
