solar system Material that is in orbit around a massive central body is an accretion disk. This disk can eventually turn into a white dwarf star. An accretion disc may eventually form planets such as the ones in our solar system.
It is believed planets form via accretion. However, due to the large size of Jovian planets, there would not be enough time for these to form via accretion. This presents the â??Jovian Problemâ?? which contends that since these type planets abound in planetary systems, there may be another way in which these planets may form.
Gravitational instability theory, is a theory that the Jovian planets are formed directly from the instabilities within the gasses around them which leads to gravitational collapse. This makes one of the four giant outer planets of the solar system, which resembles Jupiter in physical and chemicalcomposition.gravitational instabability theory -- gas and dust sticks to itself and colapses.core accretion theory -- a core of rock and ice attracts gasses.
Yes, bismuth in some form is naturally occurring. It may or may not occur in elemental form.
Some extrusive rocks such as lava and ejecta form in minutes. Stalactites may form in a few tens of years, but commonly longer. Other rocks may take millions of years, and may have to be recycled through metamorphism to attain their final form.
