Ice sheets is a lecture as part of the astrogeology series on rocky objects.

You are free to take this quiz based on the resource ice sheets at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}} and {{geology resources}} templates. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

TRUE
FALSE

2 Complete the text:

Previously, the tiger stripe regions were found to be expelling

11 Which of the following is not an astronomical cryosphere?

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

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

TRUE
FALSE

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

an albedo as high as 80%
thin water frost deposits
ice knobs
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

14 Yes or No, The tidal flexing of the ice on Europa 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?

No
Yes

15 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?

No
Yes
