8th 3.6 the sun

Areas of gas on the sun’s surface that are cooler than the gases around them are          

• solar flares
• sunspots
• solar wind
• prominences

Huge loops of gas that link different parts of sunspot regions are                

• solar flares
• supra-sunspots
• solar winds
• prominences

Large eruptions of gas from the sun out into space are              

• solar flares
• sunspots
• solar wind
• prominences

The sun produces energy through        

• fission 
• fusion
• photovoltaic cells
• photosynthesis

The sun’s layers, from innermost to outermost, are the core,                    , and convection zone.

• chromosphere 
• photosphere 
• radiation zone
• atmosphere

You see the                         when you look at an image of the sun.

• core
• chromosphere
• photosphere
• convection zone

You see the middle layer of the sun’s atmosphere, the chromosphere, at the start and end of a total eclipse.

• convection zone
• radiation zone
• photosphere
• chromosphere

The corona sends out a stream of charged particles called the              

• sunspot
• solar flare
• solar wind
• prominence

The solar wind can interact with Earth’s magnetic field to create powerful electric currents that cause        near the poles

• auroras 
• nuclear fusion 
• sun flares
• sunspots

About three fourths of the sun’s mass is            

• hydrogen
• gravity
• oxygen
• nitrogen
