Quiz[edit | edit source]


1 True or False, The leading hemisphere is the hemisphere facing the direction of the orbital motion; the trailing hemisphere faces the reverse direction.


2 The cryosphere of Enceladus is likely to include which of the following?

water in solid form

river ice
snow cover
ice caps
ice sheets

3 The science of the behavior of frozen snow is called

4 True or False, Enceladus may be a cold version of Io.


5 Chemistry phenomena associated with Enceladus are

organic compounds

6 Complete the text:

Previously, the tiger stripe regions were found to be expelling

of water-ice, fueling speculation that

seas might occur

Enceladus' frozen exterior.

7 True or False, Complex organic compounds in the geysers of Enceladus is a good indicator of possible life.

10 Which of the following is not an astronomical cryosphere?

Vatnajökull, Iceland
the last ice sheets in Europe and North America
the icy shell of Enceladus
frozen snow
the photosphere
ice sheets are in Antarctica and Greenland

11 True or False, During the last glacial period of Enceladus the Laurentide period ice sheet covered much of the mitten.


12 Which of the following is not an astronomical characteristic of ice?

an albedo as high as 80%
thin water frost deposits
ice sheets
tidal heating events
surface is composed of water ice and is one of the smoothest in the Solar System
the bright rays on the surface of Europa

13 Yes or No, The tidal flexing of the ice on Enceladus may have heated the interior and strained the lithosphere, leading to the development of cracks and horst and graben faulting, which erased the old, dark terrain on 70% of the surface?


Hypotheses[edit | edit source]
