SCIE 1920U Chapter 6: 6 The outer solar system
Document Summary
Jupiter and saturn are quite similar to each other, but fairly different from uranus and neptune. Jupiter and saturn are both made almost entirely of hydrogen and helium, with just a few percent of their masses in the form of hydrogen compounds and even smaller amounts of rock and metal. Uranus and neptune are made primarily of hydrogen compounds, such as water, methane, and ammonia with small of rock and metal. Uranus and neptune didn"t as much gas because of their distance. The visible clouds of jupiter extend downward only a few tens of kilometers into jupiter"s atmosphere. Below that, you"d find increasingly higher temperatures and pressures as you descended. Uppermost layer is gas and extend 10% the way down. The rest temperature and pressure are so extreme hydrogen is forced into a compact form that has the electrical properties of metal but flows like liquid. This is how jupiter"s magnetic field is generated.
