What happens when hydrogen nuclei fuse into helium nuclei?

Most of the sun’s energy is a result of_.

cooler, dark area of the photosphere, with a strong magnetic field

Where does the sun convert matter into energy?

What causes an aurora?

a sudden outward eruption of electrically charged particles 

Area outside of the radiative zone, where energy is carried upwards by convection

The sun is made up mostly of which element?

colored light made when charged particles from solar wind react with Earth’s upper atmosphere

The area between the core and the convective zone; where energy moves by radiation

part of coronal gas thrown into space by the sun

a loop of incandescent gas that extends above the photosphere

The outermost layer of the sun’s atmosphere  

thin layer of gases, just above the photosphere; it glows red in an eclipse

In the sun, hydrogen molecules fuse with other hydrogen molecules to form this

the nuclei of small atoms combine to form a bigger nucleus (H into He); this releases energy

Where on Earth are auroras most commonly seen?

the visible surface of the sun
