What 2 factors cause a nebula to develop into a star?
Gravity and heat cause a nebula to develop into a star.
What object is created during the formation of a star?
During the time a dense core is contracting to become a true star but before the fusion of protons to produce helium begins we call the object a protostar.
What caused the nebula to collapse and start spinning?
Shock waves from the explosion compressed the cloud of gas and dust. Compression made the cloud collapse as gravity pulled the gas and dust together forming a solar nebula. Just like a dancer that spins faster as she pulls in her arms the cloud began to spin as it collapsed.
What are the 2 reasons molecular clouds are the perfect place for star formation?
Molecular clouds are favorable locations for star formation for two reasons: low temperature and high density.
How are stars formed from Nebula?
These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction. As it collapses pressure from gravity causes the material at the center to heat up creating a protostar. One day this core becomes hot enough to ignite fusion and a star is born.
What caused the first stars to form quizlet?
Hydrogen and helium gas in these clouds formed the first stars. Supernova explosions from the first stars kept much of the gas from forming stars. Leftover gas settled into a spinning disk due to the conservation of angular momentum.
What causes a star to shine brightly Edgenuity?
What causes a star to shine brightly? … The star’s core shrinks. The star becomes a black hole.
How does gravity cause star formation?
When a nebula collapses inward which processes occur?
4. As the nebula “falls” inward gravitational potential energy is converted to heat. In the absence of a net torque the total angular momentum of a system remains constant. As the nebula collapses clumps of gas collide & merge.
What force causes particles in a nebula to condense over time?
What causes dark nebula?
What happens when a nebula begins to contract?
As the nebula contracts whatever initial tumbling/rotational motion is increased to conserve angular momentum (just like when a spinning figure skater brings in their arms). The nebula flattens into a disk. Gravitational contraction also causes the pressure to increase which causes the cloud to heat up.
Is a molecular cloud a nebula?
How does a star form from a nebula quizlet?
1b How how does a star form from a nebula? When the contracting gas and dust from nebula become so dense and hot that nuclear fusion starts. … A protostar is a contracting cloud of gas and dust with enough mass to form a star while a star is made up of large amount of gas and relatively small volume.
What happens during the nebula stage of a star?
Are stars formed in emission nebulae?
Where is star formation most likely to occur in our galaxy quizlet?
The clouds and interstellar gas and dust. Where does most star formation occur in the Milky Way galaxy today? In the spiral arms.
Which of these describes a nebula?
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula which means a “mist vapor fog smoke exhalation.” Nebulae are made up of dust basic elements such as hydrogen and other ionized gases.
Where does most of the star formation occur in a spiral galaxy?
What describes the process that causes a star to shine?
This process is called nuclear fusion. Every second a star like our Sun converts 4 million tons of its material into heat and light through the process of nuclear fusion.
What term describes the process that causes a star to shine?
The light waves from a star appear to have shorter wavelengths as the star moves toward Earth. … The gas is so hot it causes nuclear fusion and nuclear fusion causes stars to shine.
What is the main element that stars are made of Brainly?
Hydrogen is the main element that stars are made of.
How are stars formed?
What gases are in a nebula?
What causes a lot of energy to be produced in a stars core?
Many stars produce much more energy than the Sun. The energy source for all stars is nuclear fusion. … In a nuclear fusion reaction the nuclei of two atoms combine to create a new atom. Most commonly in the core of a star two hydrogen atoms fuse to become a helium atom.
What causes the flattening of the solar nebula into a disk?
Why did the solar nebula flatten into a disk? The force of gravity from the planets pulled the material downward into a flat disk. It flattened as a natural consequence of collisions between particles in the spinning nebula changing random motions into more orderly ones.
Why did the solar nebula heat up as it collapsed quizlet?
Why did the solar nebula heat up as it collapsed? As the cloud shrank its gravitational potential energy was converted to kinetic energy and then into thermal shock. … It flattened as a natural consequence of collisions between particles in the nebula changing random motions into more orderly ones.
When a planetary nebula gravitationally contracted to form our solar system what caused the central region to rotate faster and flatten into a plane?
When a planetary nebula gravitationally contracted to form our solar system what caused the central region to rotate faster and flatten into a plane? The conservation of angular momentum. Jupiter rotates once every 10 hours more than twice as fast as the Earth.
What two forces caused the solar nebula to develop into the sun?
Energy from collisions and pressure from gravity caused the center of the solar nebula to become hotter and denser.
Which two forces cause the gas and dust in nebula to form solar systems?
Solar systems form from nebulas. The gas and dust in nebulas become solar systems because of two forces: gravity and pressure. Remember that gravity pulls objects together. The particles of matter in a nebula are very small.
What causes a solar nebula to initially begin to?
Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed maybe by the explosion of a nearby star (called a supernova). … Squeezing made the cloud start to collapse as gravity pulled the gas and dust together forming a solar nebula.
Do dark nebulae form stars?
Where are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
