What else can I help you with?
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Stars develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion. This process starts in the core of the collapsing cloud, where the temperature and pressure become high enough for nuclear reactions to occur, initiating the star's life cycle.
What causes the gas and dust in a nebula to contract?
Gravity.
What force causes protostars to form?
Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
What 2 forces balance each other to keep of nebula dust and gas from collapsing or flying apart?
Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
Why does dust on the moon not float?
Dust on the moon does not float because there is no atmosphere on the moon to support floating particles. Without air resistance and buoyancy, the dust simply settles back down to the surface due to the moon's gravity.
What force pulls dust and gas together?
Gravity is the force that pulls dust and gas together in space. The gravitational attraction between particles causes them to clump together, eventually forming larger structures like stars and planets.
What causes interstellar dust and gas to start to contract and form a protostar?
A protostar forms when gravity pulls the dust and gases in a nebula together.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
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.
What pulls the gas molecules in the atmosphere down to earth?
Gravity
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Stars develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion. This process starts in the core of the collapsing cloud, where the temperature and pressure become high enough for nuclear reactions to occur, initiating the star's life cycle.
Where does the gravity of the gas giants take you?
It pulls you toward the planet's core.
What causes the gas and dust in a nebula to contract?
Gravity.
What are the steps in the life cycle of a star?
The first stage is that a star enters as a ball of gas and dust. The second stage is that gravity pulls the gas and dust into a sphere. The third sage is that as the sphere becomes denser and it gets hotter and the hydrogen changes into helium in a process called nuclear fusion.
Where are the birthplaces of stars?
"Clouds" of gas (and dust) concentrated by gravity.
Huge clouds of gas and dust floating in space?
These clouds are known as nebulae, where stars are born. Gravity pulls the gas and dust together, forming dense regions that eventually collapse to form new stars. Nebulae are of great interest to astronomers as they provide insights into the process of stellar formation.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fission?
The list of choices posted with the question doesn't include anything that fits that description. It sounds something like a "star", but in a star, it would be "fusion", not "fission".
