Question

Quizplus · Accepted Answer

The gravitational instability theory proposes that Jupiter and Saturn were formed through the direct collapse and fragmentation of the gas and dust within the solar nebula, while Uranus and Neptune formed through a combination of core accretion and gravitational instability. The gravitational instability theory suggests that the jovian planets formed directly from the collapse of the solar nebula without the need for a solid core as required by the core-accretion theory. Instead, gas and dust in the nebula clumped together and collapsed under their mutual gravitational attraction to form the gas giants we see today.
