What is the nebular theory steps?

What is the nebular theory steps?

According to the nebular theory, stars form in massive and dense clouds of molecular hydrogen—giant molecular clouds (GMC). These clouds are gravitationally unstable, and matter coalesces within them to smaller denser clumps, which then rotate, collapse, and form stars.

How many steps are in the nebula theory?

7 Steps of the Nebular Theory.

What are the seven steps to the solar nebula theory?

Terms in this set (7) Over time the remaining gas and dust begins to rotate around this center. Particles grown in size and become planetesimals. Gravity attracts more gas and dust and the solar nebula flattens out into a vast rotating disk. Accretion between planetesimals continues and planets form.

What are the 4 steps of the nebula hypothesis?

Terms in this set (5)

  • 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.

What is the third stage in nebular hypothesis?

The Nebular Hypothesis. • Step 3 (Formation of a Planetesimal): Chunks of smaller rocky material collide (irregular shape).

What is the solar nebula model?

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.

Which lists the major steps of solar system formation in the correct order?

Which lists the major steps of solar system formation in the correct order? Collapse, Condensation, Accretion.

How does a nebula form a solar system?

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. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

What are the six stages of the nebular theory?

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.
  • What are the three steps to the nebula theory?

    Temperatures continued to increase

  • The solar nebula spun faster and faster
  • The solar nebula disk flattened
  • What are the steps of nebular hypothesis?

    These are the Nebular Hypothesis of Laplace and when a theory is found unsatisfactory, the next step is to modify it in such a way as to avoid the defects that have been detected.

    What had to occur prior to nebular theory?

    The nebular theory predicted the existence of the Kuiper belt 40 years before it was discovered! Exceptions to the Rules ¥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. ¥ We call this the heavy bombardment period.
