C)observing the changes in the rings around the jovian planets.
D)observing the changes in the magnetic fields of the jovian planets.

Question

Quizplus · Accepted Answer

Measuring the mass of the rocky material in the jovian planets' cores would help determine whether the core-accretion model or gravitational instability theory is more accurate, as the core-accretion model suggests that such planets formed from the accumulation of solid materials that eventually formed a rocky core, while the gravitational instability theory predicts that the planets formed as gas and dust collapsed under their own gravity without the need for a rocky core. By measuring the mass of the rocky core, scientists can determine which theory is more accurate. Measuring the metallic hydrogen layer or observing the changes in the rings or magnetic fields of the jovian planets does not directly relate to the formation theories. The core-accretion model predicts that a solid core of rocky material forms first, which then attracts gas from the surrounding disk to form a giant planet. The gravitational instability theory suggests that a clump of gas in the disk collapses under its own gravity to form a giant planet. By measuring the mass of the rocky material in the jovian planets' cores, scientists can determine whether the amount of core material is consistent with the core-accretion model or the gravitational instability theory.
