Liquids/Liquid objects/Astronomy/Quiz

Liquid-object astronomy is a lecture and an article about a specific type of astronomical object and the techniques needed to observe it.

The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids. Credit: José Manuel Suárez.

You are free to take this quiz based on liquid-object astronomy 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}} template. 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!



1 Which of the following are cosmogonical phenomenon associated with the Sun, or solar system?

watery abyss
cold dark matter
unseen mass
Silver age

2 Complete the text:

Condensed noble gases, most notably liquid

and liquid

, are excellent radiation detection


3 True or False, The presence of a liquid may be detected by using S-waves.


4 Observations of Titan have benefited greatly from what phenomenon?

a dense, opaque atmosphere
extensive meteorite cratering
a flattening out
liquid hydrocarbon lakes
the reflected light of allotropes and compounds of sulfur

5 Which of the following are radiation astronomy phenomena associated with the apparent liquid-object Earth?

neutron emission
polar coronal holes
meteor emission

6 Why is much of the surface of Mars covered with red iron oxide dust when the rocks that compose much of its surface are blue or violet?

Mars has been systematically bombarded with small iron-nickel meteorites or micrometeorites that oxidize in its atmosphere
Mars has been frequently bombarded with hematite containing micrometeorites
asteroid impacts on Mars may have forced iron from near its core into the atmosphere and onto the surface as hematite dust that oxidized
Mars is like Earth in surface hematite composition, but Earth has much more water
precipitation from iron-rich water
