Unit 6: The Solar System and 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 Sun's 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 that emits visible light?

• 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

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

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

• solar winds
• coronal outburst
• solar flares
• auroras

What layer can be seen here?

• chromosphere
• corona
• photosphere
• core

This layer surrounds the core and transfers energy in the form of electromagnetic energy.

• chromosphere
• radiative zone
• convective zone
• photosphere

Which sun features are shown here?

• solar flares
• solar prominences
• sun spots
• aurora
