What happened to the speed of the rotation of the solar nebula as it contracted?
Contraction of insterstellar cloud. Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of interstellar gas and dust (called a nebula)(movie). As collapse proceeded, the rotation speed of the cloud was gradually increasing due to conservation of angular momentum.
What happens when a solar nebula contracts?
What happens when a solar nebula contracts? It heats up, spins faster, flattens out. What is true about solar system densities? the denser planets lie closer to the Sun.
Why does the nebula flatten and speed up as it collapses?
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. This flattening is a natural consequence of collisions between particles in a spinning cloud.
What did the contraction of the nebula lead to?
A nebula (gas cloud) slowly contracts under the mutual gravity of all of the atoms in the cloud. Contraction causes the pressure to increase which causes the cloud to heat up. Most of the mass falls into the center of mass and pressures here become the greatest.
What happens to a nebula as it contracts under the force of gravity?
the gravitational force causes a nebula to contract. Nebular theory also states that as the nebula contracts it spins faster. As the contracting nebula spins faster it flattens out into a 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.
How does the solar nebula theory explain the formation of the Earth’s solar system?
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.
How is the Nebula related to the Solar System?
Solar nebula. 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.
How did Swedenborg come up with the solar nebula hypothesis?
Written By: 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.
Are there any limitations to the nebular theory?
It is also consistent with the types of planets observed in the solar system: the small, rocky ones like Earth, closer to the Sun, and the outer gas giants. However, the theory has some important limitations: It does not explain the retrograde spin of planets like Venus and Uranus, as well as the numerous retrograde satellites out there.
Who was the first person to propose the solar nebula?
In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation, gradually pulled together by its own gravitational force and flattened into a spinning disk, gave birth to the Sun and planets. A similar model, but with the planets being formed before the Sun, was proposed by the French astronomer…
