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.
What cleared away the debris when the solar system formed?
Birth of the sun
Gravity continued to collapse the material onto the infant object, creating a star and a disk of material from which the planets would form. When fusion kicked in, the star began to
blast a stellar wind
that helped clear out the debris and stopped it from falling inward.
How did the solar nebula get cleared of material?
How did the solar nebula get cleared of material?
The radiation pressure of sunlight pushed gas particles outward
. The intense solar wind of the youthful sun pushed gas and dust outward. The planets swept up gas, dust, and small particles.
Which is the process that cleared the solar nebula away and ended planet building quizlet?
8) What process cleared the protoplanetary nebula away and ended planet building?
Very likely the solar wind during the T-Tauri stage of the star clear the last
of of the gas away, or combined with ultraviolet radiation from other stars.
Which of the following processes cleared the nebula away and ended planet building?
ANSWER: The processes which cleared the nebula away and ended planet building are as follows. 1)
The radiation pressure from the sun once it became luminous
.
What material is used in the solar nebula?
The solar nebula is initially
a thin gas of hydrogen and helium strewn with tiny dust particles
. These tiny grains serve as the building blocks of the planets. Dust grains play an important role in the evolution of any gas cloud. These grains act as condensation nuclei, on which accretion of matter occurs.
Why did solar nebula heat up as it collapses?
3) 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 is considered the edge of the solar system?
It’s not easy attempting to measure distance in space, but astronomers have been able to determine that beyond Neptune lies a ring of icy objects left over from the formation of the Solar System, known as
the Kuiper Belt
. The region extends between 30 and 50 AU (where 1 AU is the distance between Earth and the Sun).
What occurred first when our solar system was formed?
Formation. 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.
How did the solar system form in order?
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 were the three major components of the solar nebula?
The solar nebula is the cloud of gas from which our solar system was born when it collapsed under its own gravity. By using the compositions of the Sun, other stars, and interstellar gas clouds, we know that the solar nebula contained
98% hydrogen and helium
and only 2% of all other elements combined.
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.
Where in the solar system are asteroids found?
Asteroids are rocky objects primarily found in
the asteroid belt
, a region of the solar system that lies more than 2 1⁄2 times as far from the Sun as Earth does, between the orbits of Mars and Jupiter. These objects are sometimes called minor planets or planetoids.
What are the 6 stages of 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,
How does the nebular theory explain the formation of the asteroid belt?
As the nebula started to coalesce into planets,
Jupiter’s gravity accelerated the movement of nearby materials, generating destructive collisions rather than constructively
gluing material together [14]. These collisions created the asteroid belt, an unfinished planet, located between Mars and Jupiter.
How does the solar nebula theory help you understand the location of the asteroid belt?
How does the solar nebula theory help you understand the location of the asteroid belt?
Gravitational disturbances from Jupiter in the region of the asteroid belt were strong enough to disrupt accretion of planetesimals there
, so the planetesimals did not coalesce into a single planet.
