Question

Supergiant stars
a.
form from red giants.
c.
form planetary nebulae.
b.
fuse hydrogen into carbon.
d.
form supernovas.

Answer 1

As the outer layers expand from the helium core, the star becomes a red giant. The helium at the center of the star continues to increase until a helium core is formed. Nuclear reaction then begins to spread outward. As the helium core grows heavier, the core's temperature also increases, and the outer layers begin to expand until the star becomes a massive red star known as a red giant :D

Answer 2

So it forms froms a red giant

Answer 3

I think yes it forms from a red giant :D

Answer 4

All stars
a.
reflect light from the sun.
c.
produce their own light.
b.
appear to wander off their star paths.
d.
All of the above.

Answer 5

Is it D.

Answer 6

It would be c, because a star is a sun.. stars give off their own light.

(Fun fact: the light from stars we see in the sky took billions of years to reach Earth, so we're looking billions of years into the past when we look at the starry sky!)

Answer 7

It's D
In their super-hot cores, which are at many millions of degrees Kelvin, stars generate their own energy by nuclear reaction :D

Answer 8

D doesn't make sense because it can't be all of them.
A is wrong because stars give off their own light, so therefore, they don't need to reflect light from the sun.. They are suns!!
And they also don't go off their paths.. or we cannot prove that they go off their paths. Sooo the only correct answer there is that they give off their own light.

Answer 9

Ok ok so white mouse is right i need help with one more

Answer 10

Stars are driven by nuclear fusion reactions?

Answer 11

Actually wrong one

Answer 12

Extremely high temperatures and pressures are necessary for fusion reactions to take place in stars.
