What happened to the solar nebula after it collapsed?
The slowly rotating solar nebula collapsed under its own gravity to form a rapidly rotating disk, with the Sun at the center. Collisions of gas and dust within the disk concentrated the material into a thin plane.
How did the temperature of the solar nebula develop?
How did the temperature of the solar nebula develop? As the nebula collapsed, gravitational potential energy was converted into kinetic energy, and the temperature rose.
Did the nebula heat after contracting?
These became the planets. The proto-sun and proto-planets grew by accretion of the matter that was falling in toward the center of mass. The solar nebula warmed as the contraction increased the pressure. As the proto-sun grew and the pressures increased, it got hot from gravitational compression.
What conservation law is responsible for the solar nebula heating up as it collapses?
As the piece, called the solar nebula collapsed, its slight rotation increased. This is because of the conservation of angular momentum.
What happened solar nebula?
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova.
What happens to the temperature of the collapsing nebula?
As the solar nebula shrinks in size, its density, temperature and shape all undergo dramatic changes. HEATING: The temperature of the solar nebula increases as it collapses. As the cloud shrinks, its gravitational potential energy is converted to the kinetic energy of individual gas particles falling inward.
Why did the solar nebula rotate faster as it collapsed?
Initially, most of the motions of the cloud particles were random, yet the nebula had a net rotation. As collapse proceeded, the rotation speed of the cloud was gradually increasing due to conservation of angular momentum.
Why did the solar system flatten?
Eventually, a portion of this material collapses toward the center, forming a star, and the spinning cloud begins to flatten into a disk due to the rotation. It’s out of this rotating protoplanetary disk of gas and dust that planets are born, resulting in a relatively flat solar system.
Why did the solar nebula contract?
The core accretion model
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.
Which of the following did not occur during the collapse of the solar nebula?
Which of the following did not occur during the collapse of the solar nebula? hydrogen and helium. According to our theory of solar system formation, what are asteroids and comets? Which lists the major steps of solar system formation in the correct order?
How did the solar nebula get cleared of material?
How did the solar nebula get cleared of material? The radiation pressure of sunlight pushed gas particles outward. The intense solar wind of the youthful sun pushed gas and dust outward. The planets swept up gas, dust, and small particles.
What changes happened in the solar nebula as it shrank in size?
According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size? It got hotter, its rate of rotation increased, and it flattened into a disk. Which of the following types of material can condense into what we call ice at low temperatures?
What caused the planets to heat up during the early formation of the solar system?
Why was the earth so hot when it formed? Gravitational contraction/accretion: gravity caused small bodies of rock and metal orbiting the Sun to smash together. These collisions caused temperatures and pressures to increase.
Why did the solar nebula flatten into a disk quizlet?
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 nebula collapse?
The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.
How long does it take a nebula to collapse?
Explanation: For a star the size of the sun, it takes ~10 million years for the nebula to collapse. For bigger stars, it takes a shorter amount of time; as short as 100,000 years. For smaller stars, it can take far more than 10 million years.
Why didn’t the solar nebula collapsed under its own gravity?
Before the collapse, the rotation was very slow, but as it shrank, fast rotation was inevitable. It helped ensure that everything in the nebula didn’t crash into the center because the greater the angular momentum, the more spread out it would be.
What was the solar nebula gas?
Solar Nebula. Our solar system began forming within a concentration of interstellar dust and hydrogen gas called a molecular cloud. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center. The remainder of the cloud formed a swirling disk called of the solar nebula.
How hot are solar winds?
The solar wind is a stream of energized, charged particles, primarily electrons and protons, flowing outward from the Sun, through the solar system at speeds as high as 900 km/s and at a temperature of 1 million degrees (Celsius). It is made of plasma.
What is the solar nebula quizlet?
Answer: Solar nebula is a massive cloud of gas and dust that collapses into itself, compresses the gas, heats up, and eventually (assuming its massive enough) begins nuclear fusion creating a star. The dust clumps together to form planetary bodies and whatnot.
Are planetary orbits flat?
The orbits of the planets are coplanar because during the Solar System’s formation, the planets formed out of a disk of dust which surrounded the Sun. Because that disk of dust was a disk, all in a plane, all of the planets formed in a plane as well.
Are galaxies flat?
Galaxies are flat because of their rotation. All of the stars, planets and other objects in a galaxy are rotating around the core of the said galaxy, and the conservation of angular momentum allows these objects to spread outward, but not any other direction, which is why they are flat.
Is the asteroid belt flat?
Asteroid belts are also flat and so are most galaxies. In short, this pattern can be explained by a fundamental law of physics: the conservation of angular momentum.
How does the solar nebula theory explain?
The solar nebula hypothesis states that the outer planets were able to collect hydrogen within their gravity, while closer to the sun, most of the hydrogen was blown away by solar winds, leaving less hydrogen and exposing the rocky core.
How does the solar nebula theory help you understand the location of asteroids?
How does the solar nebula theory help you understand the location of asteroids? Many of the asteroids are material that would have formed a Terrestrial planet, but could not, due to gravitational pull from Jupiter and asteroids in places other than the belt are debris left over from the formation of the solar system.
What force pulls the matter in a nebula together?
Gravity Pulls Matter Together
But because the matter in a nebula is so spread out, the attraction between the dust and gas particles is very small. If a nebula’s density were great enough, then the attraction between the particles might be strong enough to pull everything together into the center of the cloud.
What are the basic differences between the terrestrial and jovian planets which planets fall into each group?
What are the basic differences between the terrestrial and jovian planets? Which planets fall into each group? Jovian planets are much larger in size and lower in density than terrestrial planets: Jupiter, Saturn, Uranus, Neptune. You just studied 69 terms!
What caused outer planets to form?
Summary: The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.
How did particles in the solar nebula eventually form Earth?
the growth of a particle by addition of material from surrounding gas, atom by atom. In the solar nebula, dust grains were continuously bombarded by atoms of gas. Condensation can increase the mass of a small grain rapidly, which converted some of the gas into solid bits of matter.
Which of the following did not occur during the contraction of the solar nebula that formed the solar system?
Which of the following did not occur during the collapse of the solar nebula? Concentrating denser materials nearer the Sun.
What processes cleared the nebula away and ended planet building?
8) What process cleared the protoplanetary nebula away and ended planet building? Very likely the solar wind during the T-Tauri stage of the star clear the last of of the gas away, or combined with ultraviolet radiation from other stars.
Which hypothesis states that a great cloud of gas and dust called nebula collapsed because of gravitational pull?
According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse.
What is the best explanation for how the solar nebula was cleared of debris quizlet?
The solar nebula was cleared of gas through the pressure of the sunlight (called radiation pressure) and through the massive solar wind. The nebula was cleared of some of the leftover debris by the Heavy Bombardment period.
Why did the temperature start to rise at the center of the solar nebula?
Why did the temperature start to rise at the center of the solar nebula? –Supernova explosions were stirring up the material there and causing turbulence. -The nebula was contracting, which increased the speed of the atoms moving in it. -Fusion reactions were beginning in the core, releasing tremendous amounts of heat.
What is the approximate chemical composition of the nebula that collapsed to form out sun and planets?
-This cloud of gas and dust that gave birth to our solar system is called the solar nebula. According to modern science, what was the approximate chemical composition of the solar nebula? C. Roughly equal proportions of hydrogen, helium, water, and methane.
How does the amount of heat released in a planet’s interior by radioactive decay change with time quizlet?
How does the amount of heat released in a planet’s interior by radioactive decay change with time? It increases with time.
Why solar system is flat?
It’s thought to have arisen from an amorphous cloud of gas and dust in space. The original cloud was spinning, and this spin caused it to flatten out into a disk shape. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.
Why does the Sun rotate slowly today?
According to our theory of solar system formation, why does the Sun rotate slowly today? A) The Sun once rotated much faster, but it transferred angular momentum to charged particles caught in its magnetic field and then blew the particles away with its strong solar wind.
Why did the solar nebula rotate faster as it collapsed?
Initially, most of the motions of the cloud particles were random, yet the nebula had a net rotation. As collapse proceeded, the rotation speed of the cloud was gradually increasing due to conservation of angular momentum.
What force caused the solar nebula collapse?
The core accretion model
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.
Why did the solar nebula flatten into a disk while it was undergoing gravitational contraction on its way to forming the Sun and planets?
FLATTENING: The solar nebula has flattened into a disk. This flattening is a natural consequence of collisions between particles in a spinning cloud. A cloud may start with any size or shape, and different clumps of gas within the cloud may be moving in random directions at random speeds.
What causes a nebula to collapse?
The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.
What collapsed nebular?
The Nebular Theory would have started with a cloud of gas and dust, most likely left over from a previous supernova. The nebula started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a Protostar .
How did the temperature of the solar nebula develop?
How did the temperature of the solar nebula develop? As the nebula collapsed, gravitational potential energy was converted into kinetic energy, and the temperature rose.
What happens if solar wind hits Earth?
The Sun releases a stream of charged particles called the solar wind. On the Earth’s surface, we are protected from this barrage by the magnetosphere – a bubble created by the Earth’s magnetic field. When the solar wind hits the magnetosphere, waves of energy are transferred along the boundary between the two.
Are solar winds hot or cold?
Summary: When the sun expels plasma, the solar wind cools as it expands through space — but not as much as the laws of physics would predict. Physicists now know the reason.
What happens when a solar nebula collapses quizlet?
The solar nebula collapses and begins to rotate, it becomes more dense at the center, the gas and dust in the central part begins to cool as dust particles form. The particles begin then to form larger particles. They are the particles that collided to form things of boulder and asteroid size.
What happened to the solar nebula quizlet?
By the time planetesimals grew to a large enough mass to hold onto an atmosphere, the solar nebula had been blown away. There was no material to create planetesimals beyond the orbit of Neptune. By the time planetesimals grew to a large enough mass to hold onto an atmosphere, the solar nebula had been blown away.
