What are the outer planets?

Jupiter, Saturn, Uranus, and Neptune

How do massive stars end their lifecycle?

collapse to form a neutron star

Order the following steps.

Stellar nebula, blue star, supernova, black hole

If an average star is not expanding into a red giant, which statement must be true?

There is a balance between gravity pushing in and energy released out

Based on what you know, if a 9th planet were discovered past Neptune what would we expect it to be made of?

Light elements (hydrogen, helium), Ice

What happens to blue star when fusion stops?

The iron core collapses and lots of energy is released in an explosion

Order the following steps for our Sun.

Stellar nebula, our sun, red giant, planetary nebula

What happens during Nuclear Fusion

Lighter atoms smash together to form heavier new elements and energy

4
If an average star is not expanding into a red giant, which statement must be true?
There is a balance between gravity pushing in and energy released out
The gravity pushing in on is greater than the energy pushing out.
The gravity pushing in on is less than the energy pushing out.
There is a balance between gravity expanding out and energy being absorbed

13
What does it mean that a star is "dead"?
It is no longer shining light
Fusion has stopped
It is too big
the star is fusing heavier elements
14
What happens to blue star when fusion stops?
Nothing.
The iron core collapses and lots of energy is released in an explosion
They burn out
The core collapses and outer gas layer floats away
15

18
What happens during Nuclear Fusion
Atoms get burnt up like wood in a fire to release energy
Atoms split apart and release energy
Heavier atoms smash together to form lighter new elements and energy
Lighter atoms smash together to form heavier new elements and energy
