Rocky the Rockhound guides kids of all ages into the wonderful world of rocks. This small, 33 page book explores the difference between minerals, crystals, and rocks. It touches on the history of rock formations, dating back to the precambrian era over 4.5 billion years ago, and discusses how to identify rocks and minerals (via luster, hardness, cleavage, streak). A large part of the book highlights well known rocks and minerals, and offers some non-metaphysical information about them.
