Have you ever wondered what a badland is? What about a gulch? Do you wonder what an isthmus is? Or a seamount? What about the difference between a plateau and a plain, or a knob and a knoll? Well, here are the answers! The sixty-three entries from A to Z describe the earth's features -- its physical geography -- from the highest mountain peak to the deepest ocean trench, in clear, concise terms. Each entry is beautifully illustrated in full color. This is a perfect introduction to the dramatic and fascinating face of the vast world around us. The author and artist of the best-selling MAPS & GLOBES team up again, this time to prove that geography can indeed be an adventure.
