- What are Jovian planets made of?
- Jovian planets, like Jupiter & Saturn, are made mostly of H and He gas. Uranus & Neptune are mostly made of H compounds.
- What are Jovian planets like on the inside?
- On the inside, Jovian planets have layered interiors with very high pressure and cores made of rock, metals, and hydrogen compounds. The very high pressure in Jupiter & Saturn can produce metallic hydrogen.
- What is the weather like on Jovian planets?
- On Jovian planets, the weather itself contains strong storms and winds. There are also multiple cloud layers that determine the color of the Jovian planets.
- What kinds of moons orbit the Jovian planets?
- Moons of many sizes orbit the Jovian planets. The level of geological activity depends on the size.
- Why are Jupiter's Galilean moons geologically active?
- Jupiter's Galilean moons are geologically active due to the drive from the tidal heating. This then leads to Io's volcanoes and ice geology on other moons.
- What geological activity do we see on Titan and other moons?
- The geological activity we see on Titan is that the only moon with a thick atmosphere. Many other icy moons show signs of geological activity.
- Why are Jovian moons more geologically active than small rocky planets?
- Jovian moons are more geologically active than small rocky planets because the ice melts and deforms at lower temperatures, enabling tidal heating to drive activity.
- What are Saturn's rings like?
- Saturn's rings are made up of countless individual ice particles and are extremely thin with many gaps.
- Why do the Jovian planets have rings?
- Jovian planets have rings because the ring systems of the Jovian planets are much fainter with smaller, darker, less numerous particles. The ring particles are probably debris from moons.
- Who predicted volcanoes on Io?
- Stan Peale, Patrick Cassen, and R.T. Reynolds were the three gentleman that predicted volcanoes on Io.

Stanton Peale was my professor at UCSB!
