Core accretion theory?

This belongs in astronomy. It's a theory of how solar systems have come to be. Basically, clouds of gas draw together and form an accretion disc (which lies in a plane equal to the planets' axes). In the center a sun is created from the large amount of particles gathering there. Elsewhere particles gather and form larger particles, which collide and gain size over time. After a long, long time a solar system has been created. All the details are not known, and this was probably the most simplistic explanation of the theory possible, try searching for accretion disc.


Sentence usage of the word accretion?

The mountain range formed over millions of years through the accretion of sediment and rock particles. The artist's style evolved through the accretion of various influences and experiences. The accretion of dust on the furniture indicated that no one had been in the room for quite some time.


What are the steps of the nebular theory?

The steps of the Nebular Theory consist of: The collapse of the nebula and formation of the protoplanetary disk and protosun. The condensation of planetessimals. The Accretion of planetessimals to form planet seeds. The Formation of Jovian planets through nebular capture and the solar wind of young sun clears away the remaining gas.


What are some problems with accretion theory?

The main problem at this point is in explaining how the various bodies in the solar system came to occupy the orbits that they do. For instance, for a large gaseous body like Jupiter to form, it would have to have started out as a much smaller and denser body. But classical models have such bodies coalesce much closer to the Sun than Jupiter currently is. One of the hypotheses accounting for this is that Jupiter started out closer to the Sun, but was then flung in a wider orbit as a result of a series of gravitational encounters.


What is accreation?

"Accretion" refers to the process of growth or accumulation of material over time. In astronomy, it commonly refers to the accumulation of gas and dust by a celestial object, such as a planet or star, through gravitational attraction. Accretion plays a significant role in the formation and evolution of various celestial bodies in the universe.

What is it called when a core of rock and ice attracts gases in space?

It is called accretion. The term is also used for the formation of a stellar disk that begins the process of forming planets around a star.


What are the three theories on the origin of the earth?

The three main theories on the origin of the Earth are the nebular hypothesis, the giant impact hypothesis, and the core accretion theory. The nebular hypothesis proposes that the solar system formed from a rotating cloud of dust and gas, while the giant impact hypothesis suggests that Earth formed from a collision between a Mars-sized protoplanet and the early Earth. The core accretion theory posits that planets formed from the gradual accumulation of solid particles in a protoplanetary disk.
