Star Life Cycle and structure

All stars start as gas and dust in a(n)

• nebula
• black hole
• red giant
• black dwarf

After the main sequence, a low mass star becomes a

• black dwarf
• protostar
• red giant
• supergiant

After the main sequence, a high mass star becomes a

• black dwarf
• protostar
• red giant
• supergiant

After a supergiant, a high mass star explodes and forms a

• supernova
• red giant
• black hole
• planetary nebula

A high mass star can end as this stage, which is so dense that not even light can escape!

• black dwarf
• white dwarf
• supernova
• black hole

When a nebula heats up, a "baby" star forms in the middle. It is called a

• supernova
• supergiant
• white dwarf
• protostar

Which of the following is NOT a final stage of a star. 

• black hole
• black dwarf
• neutron star
• red giant

A star is born and lit up  when ______ happens and provides the star with energy that it will use for millions of years.

• nuclear fusion
• gravity
• hydrogen
• iron
