As we observe this earth, we see great beauty and marvelous balance, but we can never fully understand our present earth without knowing its past. Only those who do recognize its true past can make sense out of the evidence that we observe in the present. This book will teach you: What really carved the Grand Canyon, how thick the earths crust is, why the earth is unique for life, fossilization and the age of the dinosaurs, the powerful effects of volcanic activity and much more. Beautifully illustrated, HB, 80 pages, recommended for grades 7-9.
