The volcanoes of Io is a lecture regarding a specific astronomical object (Io) and its volcanoes. It is an offering from the school of geology and the astronomy department of the school of physics and astronomy.

You are free to take this quiz based on the volcanoes of Io 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 {{astronomy resources}} and the {{geology resources}} templates at the bottom of the page. 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!
