Currently the best theory is the Nebular Theory . This states
that the solar system developed out of an interstellar cloud
How does the nebular theory form the 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.
How does the nebular theory describe the formation of the solar system 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 role did gravity play in the formation of our 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. … Small particles drew together, bound by the force of gravity, into larger particles.
Which two observed characteristics of our solar system are explained by the nebular hypothesis?
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.
What was the major influence in the formation of the solar system?
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. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
What are the steps in the solar system formation?
- Contraction: The cloud starts collapsing under its own gravity; over 100,000 years, it shrinks down to 100 AU, heats up (thermal energy), and compresses in the center.
- Accretion disk: The matter around the center spins up and flattens into a disk, while heat vaporizes the dust.
What caused our solar system to form?
The Sun and the planets formed together, 4.6 billion years ago, from
a cloud of gas and dust called the solar nebula
. … After the Sun ignited, a strong solar wind cleared the system of gas and dust. The asteroids represent the rocky debris that remained.
What is the evidence of nebular theory?
What Evidence do we have of a Nebular Theory-type development? We have
observed discs of gas and dust around other stars
. We can also see evidence of stars and planets forming in clouds of gas and dust; young planet systems in the making are called Proplyds.
What are the four theories of the solar system?

What is the formation of the universe?
Our universe began with
an explosion of space itself – the Big Bang
. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
What is solar system Short answer?
:
the sun together with
the group of celestial bodies that are held by its attraction and revolve around it also : a similar system centered on another star.
What can we learn about the formation of our solar system by studying other stars?
Explain. Observing other stars allows us
to see that different types of planets and planet formation begins in the same location
. Observing other stars can also help us understand how planets formed in systems with stars similar to our own Sun by observing the many stages those stars go through.
What holds the solar system together?
Our Sun – the heart of our solar system – is a yellow dwarf star, a hot ball of glowing gases.
Its gravity
holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit.
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.
