Why Did The Solar Nebula Heat Up As It Collapsed

Why Did The Solar Nebula Heat Up As It Collapsed?

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.

What happens when a solar nebula collapses?

When this dust cloud collapsed it formed a solar nebula – a spinning swirling disk of material. At the center gravity pulled more and more material in. … Some of them grew big enough for their gravity to shape them into spheres becoming planets dwarf planets and large moons.

Why did the temperature start to rise at the center of the solar nebula quizlet?

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 three changes occurred as the solar nebula was collapsing?

According to our theory of solar system formation what three major changes occurred in the solar nebula as it shrank in size? (blue) It got hotter its rate of rotation increased and it flattened into a disk. (red) It gained energy it gained angular momentum and it flattened into a disk.

Did the solar nebula heat up as it collapsed?

Why did the solar nebula heat up as it collapsed? A) Nuclear fusion occurring in the core of the protosun produced energy that heated the nebula. … As the cloud shrank its gravitational potential energy was converted to kinetic energy and then into thermal energy.

What physical process is the reason why solar nebulas are flat?

As the nebula shrinks its rotation causes it to flatten into a disk. Much of the material is concentrated in the hot center which will ultimately become a star. Away from the center solid particles can condense as the nebula cools giving rise to planetesimals the building blocks of the planets and moons.

Why did the solar nebula collapse to form the Sun and the planets quizlet?

What was it made of and where did it come from? 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.

Why did the temperature start to rise at the center of the solar nebula group of answer choices?

gravity. Why did the temperature start to rise at the center of the solar nebula? The nebula was contracting which increased the speed of the atoms moving in it.

What force ensured that once the solar system began collapsing it continued to do so?

An interstellar cloud of gas that is known as the solar nebula collapsed under its own gravity. The collapse may have been caused by a cataclysmic event. After that gravity allowed the collapse to continue.

Which of these quantities changed as the solar nebula shrank?

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.

What happened to the speed at which the solar nebula rotated as it collapsed?

As collapse proceeded the rotation speed of the cloud was gradually increasing due to conservation of angular momentum. … The solar nebula became hottest near the center where much of the mass was collected to form the protosun(the cloud of gas that became Sun).

Which of the following did not occur during the collapse of the solar nebula quizlet?

Which of the following did not occur during the collapse of the solar nebula? Concentrating denser materials nearer the Sun.

What happened as the nebula become denser due to increasing gravitational force?

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.

What does the solar nebula imply it created?

Solar nebula gaseous cloud from which in the so-called nebular hypothesis of the origin of the solar system the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart.

What does solar nebula theory imply?

Currently the best theory is the Nebular Theory . This states that the solar system developed out of an interstellar cloud of dust and gas called a nebula . … The Nebular Theory would have started with a cloud of gas and dust most likely left over from a previous supernova.

Why did the nebula spin faster as they shrink or collapse?

As a ball of dust and gas contracts under its own gravity it begins to shrink and its core begins collapsing faster and faster. This causes the core to heat up and to rotate.

Why is the solar system flat?

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.

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 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.

Why didn’t the solar nebula collapse completely 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 clues do we have about what triggered the collapse of the solar nebula to form our solar system?

According to one longstanding theory our Solar System’s formation was triggered by a shock wave from an exploding supernova. The shock wave injected material from the exploding star into a neighboring cloud of dust and gas causing it to collapse in on itself and form the Sun and its surrounding planets.

What is the solar nebula quizlet?

solar nebula. a rotating cloud of gas and dust from which the sun and planets formed. nuclear fusion. the process by which nuclei of small atoms combine to form a new more massive nucleus the process releases energy.

How is the solar nebula theory supported by the motion of solar system bodies?

How is the solar nebula theory supported by the motion of solar system bodies? All of the planets orbit the sun near the sun’s equatorial plane. All of the planets orbit in the same direction that the sun rotates. … Radiometric dating of rock samples indicates that the solar system formed about 4.56 billion years ago.

What caused our solar nebula to contract and spin eventually creating planets?

What caused our solar nebula to contract and spin eventually creating the planets? … Formation of proto-planets.

When the solar nebula shrank in size which change occurred last during planet formation?

It formed from the material ejected from Earth in a giant impact. 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.

Who proposed the theory of solar system?

The main idea of the solar system was proposed by the Polish astronomer Nicolaus Copernicus (1473-1543) who said that “the Sun is the center of the Universe” and made the planets move around it in perfect circles (in his book entitled “On the Revolution of the Celestial Spheres” written in Latin and published in 1543 …

What was the material from which the solar system formed?

The Sun and the planets formed together 4.6 billion years ago from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula.

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.

What is the best explanation for how the solar nebula was cleared of debris?

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.

Which of the following features of the solar system does the solar nebula hypothesis explain?

The disk was the solar nebula and the bulge became the Sun. Which of the following features of the Solar System does the solar nebula hypothesis explain? … the Sun’s heat made it difficult for ices and gases to condense near it.

What happens when a nebula collapses?

Nebulae are made of dust and gases—mostly hydrogen and helium. … Eventually the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

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.

How does the solar nebula theory explain the orbits of the major planets?
