What else can I help you with?
Stars are formed from clouds of dust and gas called?
Stars. That is how stars are formed. They form from nebulae.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
Is it true people did not realize that the stars formed patterns until the 1900s?
No. Ancient peoples attributed patterns to the stars.
Is it true that Saturn is famous for its rings?
Yes It is famous for its rings. they are formed from dust and tiny ice crystals.
Stars and planets are formed what the nebula collapses creating spinning balls of matter?
True
Stars and planets are formed when the nebula collapses creating spinning balls of matter.?
true
Is it true that the number of stars is declining as stars burn out?
Yes, stars do eventually burn out and die, decreasing the overall number of stars in the universe. However, new stars continue to form through processes like stellar birth in nebulae, so the total number of stars in the universe remains relatively constant on a larger scale.
What is the role that gravity played in the formation of planets stars and solar systems and in determining their motions?
There is no doubt that planets, stars, and solar systems could not ever have formed without gravity. All of these astronomical objects condensed out of clouds of interstellar gas and dust, under the influence of gravity. It is also true that planets orbit stars only because of the gravitational attraction of those stars.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.
Are noble gases inert gases true or false?
TRUE (apex)
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.
How many stars existed on the beginning of the Universe?
If the big-bang theory is true, the stars, planets, and other universal bodies were progressively formed, so there were much less stars than we have today, and the fomation of new stars is compensated by the death of others.
