The internal structure of the two largest Jovian planets (from the center outward) is a(n)
A) iron-nickel core (from which the Jovian magnetic field arises), a semifluid rocky mantle, and a solid rocky crust covered by a thin atmosphere.
B) rocky core covered by a very thick gaseous hydrogen and helium layer.
C) rocky core, a liquid "ice" layer that may overlap with the rocky core, a liquid metallic hydrogen and helium layer, and an ordinary hydrogen and helium gaseous layer.
D) rocky core, a liquid methane mantle, and a gaseous methane atmosphere.

Question

Quizplus · Accepted Answer

The two largest Jovian planets, Jupiter and Saturn, have a complex internal structure that includes a rocky core, a layer of liquid "ices" (which may include water, ammonia, and methane in liquid form), a layer of liquid metallic hydrogen and helium, and an outer layer of gaseous hydrogen and helium. This structure supports the generation of their strong magnetic fields and accounts for their unique physical characteristics.
