How does gravity and nuclear fusion affect a stars size?
JenniNajera
Gravity will cause a star to become smaller, because it pulls matter towards the star's core and causes it to contract. On the other hand, nuclear fusion will cause a star to become larger, because it produces an outward pressure, pushing the star's matter outwards and causing it to expand.

Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, stars are born when gravity pulls gas and dust together from a nebula.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
Can planets generate nuclear fusion?
No. That's precisely the main difference between planets and stars - that stars can have nuclear fusion, planets not.
What does Nuclear Fusion have to do with stars?
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'
What are all-stars driven by?
Stars are driven by Nuclear Fusion.
How does gravity effect the stars?
Please check the difference between the words "affect" and "effect". In this case, it should be "affect". Gravity keeps the stars together in the first place. It compresses them so much that they become hot and dense in their cores; enough so to start nuclear fusion.
Do stars combust?
Stars are not powered by combustion; they are powered by nuclear fusion, which is a fundamentally different and far more energetic process.
What is the process by which stars burn brightly?
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
How did they become stars?
Gravity pulls the material together and it heats up to the point when self sustaining nuclear fusion starts.
Are stars nuclear powered?
yea by nuclear fusion
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
Hydrogen bombs and stars both produce energy with nuclear?
Nuclear fusion.
How do fusion and gravity maintain stars in their current form?
Fusion pushes out, Gravity pulls in.

Stars are powered by nuclear fusion
What are powers stars?
Stars are powered by nuclear fusion

Nuclear Fusion
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
