How can it be “geology” when that term is specific to planet Earth?
Okay, I’ll concede Dictionary.com uses “earth” in almost every definition.
But what is the term for the ‘geology’ of Mars, if not geology?
Webster’s is not as specific:
a : a science that deals with the history of the earth and its life especially as recorded in rocks
b : a study of the solid matter of a celestial body (as the moon)
That’s a new one to me. Wouldn’t it be Terrology if it was earth specific?
Because "astrology" is already taken.
