Exam 9: Small Bodies of the Solar System

What material has been seen erupting from the surface (see the image below)of the icy moon Enceladus,and why?

The likely source of comets that mostly have orbits of extreme tilt with respect to the ecliptic is:

Where does Titan's thick,nitrogen-rich atmosphere (see the image below)come from?

The radiant of a meteor shower is:

How do particles from Enceladus wind up in Saturn's E Ring?

Suppose we discover a comet whose orbit was very highly eccentric,retrograde,had a very large tilt with respect to the ecliptic plane,and a period of 2,000 years.Where is the most likely place of origin for this comet?

Eris and Ceres are examples of:

The one orbital characteristic both short- and long-period comets share is:

Why does the dust tail separate from the ion tail?

Which group of meteorites represents the conditions in the earliest stages of the formation of the Solar System?

The type of meteorites most likely to have originated from the outer layers of differentiated planetesimals come from

The surface of the dwarf planet Eris has very high albedo and is covered with:

Cometary nuclei are most likely:

In the figure below,label each portion of the comet.

Most comets originate:

Europa is a very interesting moon that NASA is considering visiting with a spacecraft in order to search for signs of life.What is it about this moon that makes it so interesting,and what surface features give us clues about its interior?

Describe two modern-day events when comets or asteroids collided with a planet.Cite the planet,give the approximate year when the collision occurred,and describe the major consequences of the collision.

When a comet comes close to the Sun,its volatile ice sublimates and transforms directly from the solid to ________ phase.

A comet having an orbit of 50 years would likely have come from the:

Antarctica is the best hunting ground for meteorites for all of the following reasons EXCEPT:
