Answer:
Answers:
Jupiter and the other Jovian planets are sometimes called "gas giants." In what
sense is this term misleading?
The materials they are made of are not the kinds of things we
usually think of as gases.
They have exteme temperature and pressures that result in states
of matter other than gaseous.
They are not in any sense "giants."
Actually, it's a great description, because these worlds are big and
gaseous throughout.
The materials they are made of are not the kinds of things we
usually think of as gases.
