Great E-Book
I found this book to be very informative over rocks and even delved into other aspects such as Earth history and Earth cycles. There was a lot of content covered in this ebook and I loved the interactive activities that coincide with the lessons. The only think I wish would be listed was the sub categories of each lesson for each chapter so I could better track my progress (maybe a progress completion bar).
