In order for the disk instability model to be able to account for the formation of the Jovian planets,
A) the rocky material would have to be confined completely to the inner part of the solar system.
B) the gas in the nebular disk would have to be at a very high temperature.
C) the gas in the nebular disk would have to be clumpy rather than smooth.
D) the gas in the nebular disk would have to be mostly methane and ammonia rather than hydrogen and helium.

Question

Quizplus · Accepted Answer

The disk instability model requires the gas in the nebular disk to be clumpy so that these clumps can start to contract and eventually form Jupiter-sized gas giants. Rocky material being confined completely to the inner part of the solar system (choice A) and gas being at a very high temperature (choice B) are not specifically required for this model to work, and the gas being mostly methane and ammonia (choice D) is not a necessary condition for the formation of Jovian planets.
