Crater astronomy is a lecture included as a quiz-section minilecture in the radiation astronomy course on the principles of radiation astronomy.

You are free to take this quiz based on crater astronomy at any time.

To improve your scores, read and study the lecture, the links contained within, listed under See also, External links, and in the {{principles of radiation astronomy}} 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.

26 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
