Protostar

a)

A massive star can collapse and become an extremely dense, hot and bright star. Sometimes, neutron stars will turn into pulsars.

b)

All the hydrogen in a super massive star is converted to helium and the core collapses and then the star expands.

c)

A smaller star will run out of atoms it can fuse because it's core will be primarily carbon and oxygen and will shrink, cool and fade

d)

The gas particles run into each other, create heat and form a clump when the gas and dust in a nebula start condensing

2.

Giant cloud of gas where a star can form

(a)  

3.

Carbon and iron can start to fuse in what type of star?

a)

Super Red Giant

b)

"Typical" Red Giant

c)

Protostars

d)

Main Sequence

4.

All the hydrogen in the star is converted to helium and the core collapses and then the star expands, but iron and carbon DO NOT FUSE.

(a)  

5.

Black Hole

a)

The largest stars will run out of atoms it can fuse and it will collapse on itself.  Due to its massive size, gravity will take over, allowing nothing, including light, to escape.

b)

All the hydrogen in a super massive star is converted to helium and the core collapses and then the star expands

c)

A smaller star will run out of atoms it can fuse because it's core will be primarily carbon and oxygen and will shrink, cool and fade

d)

Gravity compression gives the star its shape

6.

A massive star can collapse and become an extremely dense, hot and bright star... almost like a mini explosion, but still a star shaped heat ball.

(a)  

7.

White Dwarf

a)

A smaller star will run out of atoms it can fuse because it's core will be primarily carbon and oxygen and will shrink, cool and fade

b)

Gravity compression gives the star its shape

c)

The gas particles run into each other, create heat and form a clump when the gas and dust in a nebula start condensing

d)

Carbon and Iron can be fused together

8.

Gravity compression and nuclear fusion are in balance to give the star its shape for almost 10 billion years

(a)  

9.

A star runs out of fuel it can fuse and it collapses and then explodes into a planetary nebula.  Any element in the universe heavier than iron is formed in the massive explosion

(a)  

10.

Fusion of heavier elements inside a star...

a)

All the hydrogen in a super massive star is converted to helium and the core collapses and then the star expands creating more than just H and He in the making

b)

A massive star can collapse and become an extremely dense, hot and bright star

c)

A smaller star will run out of atoms it can fuse because it's core will be primarily carbon and oxygen and will shrink, cool and fade

d)

The gas particles run into each other, create heat and form a clump when the gas and dust in a nebula start condensing
