Halogen minerals is a lecture from the school of geology and the radiation astronomy department. It is about solid, crystalline substances that occur in and compose astronomical objects including the Earth. It focuses on materials containing large amounts of halogens that may occur on the surface of or associated with some astronomical objects.

You are free to take this quiz based on halogen minerals at any time.

To improve your scores, read and study the lecture, the links contained within, listed under See also and 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 using more familiar points of view, or be creative with association.

Enjoy learning by doing!
