When a star begins to run out of fuel, what two types of stars can it become?

• Supernova or Neutron Star

• White dwarf or Supernova

• Red Giant or Supergiant

• Supernova or Black Hole

Someday the sun will leave the main sequence and become a red giant star. As a red giant, it will be fusing ___ in its core. It will also swell up, becoming larger in diameter. It also cools.

• helium into carbon

• helium into hydrogen

• hydrogen into helium

What is the first stage of a main sequence star turning into a red giant?

• Helium fuel depletes

• Hydrogen fuel depletes

• The core explodes in a supernova

What is a Red Giant?

• A large, bright, cool star

• A small, bright, cool star

• A burnt out white dwarf star

• A young star that has just started the fusion of hydrogen

A low mass main sequence star expands into a red giant and will grow more than 100 times it's original size.

Why does the fusion of helium into carbon not take place in low-mass stars?

• Not hot enough to fuse hydrogen

• Not hot enough to fuse iron

• Not hot enough to fuse helium

• Not hot enough to fuse beryllium

In a red giant, hydrogen fusion occurs in:

• The core

• A shell and the core

• A shell

• Neither a shell nor the core

Red giants fuse:

• Hydrogen to helium in the core

• Helium to carbon in a shell

• Hydrogen to helium in a shell
