Minerals/Metals/Alkaline earths/Quiz

Alkaline earth minerals is a lecture from the school of geology. It is about solid, crystalline substances containing the alkaline earth elements of the periodic table that occur in and compose astronomical objects. It focuses on materials that may occur on the surface of or associated with some astronomical objects.
