Exam 18: The Outer Solar System

Choose the correct term to make the statement correct: Rising and sinking of gas within the zones and belts are examples of ____ (conduction, convection, radiation) ____.

____________ is the smallest of the large moons of Uranus and its surface has features called ovoids. These ovoids may have been formed by the upheaval of material by convection in the interior.

The graph below plots the escape velocity of several solar system objects along the vertical axis and the surface temperature along the horizontal. The lines plotted in the figure are the fastest speeds of gas particles as a function of temperature for various gases. Which of the gases plotted in this diagram could be retained by Miranda?

What is one possible reasons Jupiter and Saturn radiate more energy than they receive from the Sun?

The ____________ of a planet is the region around the planet where the magnetic field is able to deflect the solar wind and other charged particles.

Why do astronomers think that Saturn's rings are not a permanent feature that has existed since the formation of the planet?

Triton orbits in the same direction as Neptune's rotation.

The Roche limit is the

Saturn's rings are

Which of these are nearly 90 degrees to the orbit plane of Uranus?

Both Jupiter and Saturn contain liquid metallic hydrogen.

Which of these wins the prize as the blandest appearing planet as revealed visually by space probes?

On its icy surface, Uranus's satellite Ariel has smooth valleys with few craters. Other areas are rough with many craters. Based on this, it can be concluded that

Jupiter's intense magnetic field traps high-energy particles from the solar wind and forms a radiation belt around the planet.

What causes the geological activity seen on some of the inner moons of Jupiter?

The graph below plots the escape velocity of several solar system objects along the vertical axis and the surface temperature along the horizontal axis. The lines plotted in the figure are the speeds of the fastest gas particles as a function of temperature for various gases. Which of the objects in this diagram has the greatest surface temperature?

Pluto is an example of a plutino.

Use the above graph to determine which Jovian planet has a clear hydrogen atmosphere above 100 km at a temperature of 150 K.

The atmosphere of ____________ contains mostly nitrogen with some methane.

Saturn's belts and zones are obscured by haze high in its atmosphere.
