What does the nebular theory explain quizlet?

Nebular Theory: states that the Sun, when forming in the nebula, generated planets, asteroids, etc from spinning disk of matter called the accretion disk. Simultaneously, gravity pulls cloud into spherical shape and it begins rotating. 3 In the flattened disc, gas particles condense into solid particles.

What does the nebular model explain?

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun.

What does the nebular theory predict?

The nebular theory predicted the existence of the Kuiper belt 40 years before it was discovered! There were many more leftover planetesimals than we see today. Most of them collided with the newly-formed planets & moons during the first few 108 years of the Solar System.

How does the nebular theory explain the formation of our solar system?

The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud—the solar nebula. – (Nebula is the Latin word for cloud.) Kant and Laplace proposed the nebular hypothesis over two centuries ago.

What are the two major types of planets?

Planets are generally divided into two groups: the terrestrial and the giant planets.

What are the six stages of the Nebular Theory?

Nebula, protosun forming, spinning planetary disk, protoplanets forming,

Shock waves from a nearby supernova explosion.

It also begins to flatten.

Protosun.

When the gravitational forces begin to fuse hydrogen into helium (fusion)

Protoplanets.

Inner protoplanets – most of their lightweight gases are boiled away,

What are the five steps of the nebular hypothesis?

step one(4) -The solar nebula consisted of. -hydrogen,
step two(2) -A disturbance.
step three(2) -The solar nebula assumed a flat, disk shape.
step four(2) -Inner planets began to form from metallic.
step five(2) -Larger outer planets began forming from fragments.

Why is the nebular theory important?

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 . This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects.

What are the steps to the nebular theory?

What are the 4 classifications of exoplanets?

So far scientists have categorized exoplanets into the following types: Gas giant, Neptunian, super-Earth and terrestrial.

Which is the modern version of the nebular hypothesis?

Nebular hypothesis. The widely accepted modern variant of the nebular hypothesis is the solar nebular disk model ( SNDM) or solar nebular model. It offered explanations for a variety of properties of the Solar System, including the nearly circular and coplanar orbits of the planets, and their motion in the same direction as the Sun’s rotation.

How is the solar nebula related to the Solar System?

Solar Nebular Hypothesis: our solar system formed out of the remains of a nebula that condensed into the sun, planets, and moons of our solar system The sun: the center of the disk of spinning gas formed a mass that, through centripetal force and gravity, created a mainly hydrogen mass of heat and energy.

Which is the most widely accepted model of the Solar System?

It is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems ). It suggests that the Solar System is formed from the nebulous material.

When did Pierre Simon Laplace propose the nebular hypothesis?

Pierre-Simon Laplace independently developed and proposed a similar model in 1796 in his Exposition du systeme du monde. He envisioned that the Sun originally had an extended hot atmosphere throughout the volume of the Solar System.
