Planets form from a solar nebula through a process called accretion. As the nebula, composed of gas and dust, collapses under gravity, it begins to spin and flatten into a rotating disc. Within this disc, particles collide and stick together, gradually forming larger bodies called planetesimals. Over time, these planetesimals coalesce to create protoplanets, which can further merge to form the planets we see today.
What else can I help you with?
The solar nebula was 98?
The solar nebula was a rotating cloud of gas and dust that formed our solar system about 4.6 billion years ago. It consisted mostly of hydrogen and helium, with traces of other elements. Over time, gravity caused the nebula to collapse and form the Sun and the planets.
How does the solar nebula theory explain the dramatic density difference between the terrestrial and jovian planets?
The solar nebula theory explains that planets are formed by solid bits of matter. What that matter is entirely dependent on the gas and substances available. The terrestrial planets in our solar system were located in the inner part of the solar nebula. This means that the temperatures were too high for the gas to condense into solids, leaving metals and silicates as the only solids from which the small and dense terrestrial planets could form. Meanwhile, the temperatures in the outer solar nebula were cold enough for the gases to form solid ice. The large Jovian planets then formed from the large amounts of ice particles available and were able to capture gas directly from the solar nebula because of how large they were.

How does a nebula developes into a solar system?
A nebula develops into a solar system through the process of gravitational collapse. As the nebula contracts due to gravity, it starts to spin and flatten into a spinning disk. Within this disk, the material begins to clump together and form planetesimals, which eventually coalesce to form planets, moons, and other objects in the solar system.
Does the solar nebula still exist?
The solar nebula, which was a vast cloud of gas and dust that formed our solar system about 4.6 billion years ago, no longer exists in its original form. Over time, it collapsed under gravity to form the Sun, planets, moons, and other solar system bodies. However, remnants of the solar nebula can still be found in the form of the Kuiper Belt, the Oort Cloud, and interstellar gas and dust, which continue to exist in space.
What is a solar nebula and how does it relate to the formation of earth?
A solar nebula is a cloud of gas and dust in space that serves as the precursor to star and planet formation. About 4.6 billion years ago, our solar nebula collapsed under gravity, leading to the formation of the Sun at its center and the surrounding protoplanetary disk. Within this disk, particles collided and coalesced to form planetesimals, which eventually merged to create the planets, including Earth. Thus, the solar nebula is fundamental to understanding how Earth and the other planets in our solar system formed.
How do the planets of the solar system form?
Out of an accretion disk leftover from the solar nebula. Small particles bump together and collect until they form planets.
What did the solar nebula make?
Planets.

The extra matter at the center of the solar nebula became the?
Inner planets
Which aspect of the nebula hypothesis accounts for the planets orbiting in the same direction and plane?
The conservation of angular momentum during the collapse of the primordial solar nebula is the aspect that accounts for the planets orbiting in the same direction and plane. As the nebula contracted and flattened into a spinning disk, this momentum caused the planets to form in a singular direction and plane, similar to the rotation of the original nebula.
What would be the implications for the formation of the solar system if the solar nebula lacked any angular momentum initially?
If the solar nebula had no angular momentum initially, it would not have been able to form a spinning disk, which is necessary for the formation of a solar system. This spinning motion is what causes the material in the nebula to flatten into a disk shape, leading to the formation of planets and other celestial bodies. Without angular momentum, the material in the nebula would not have been able to come together to form a solar system as we know it.
