The Grand Canyon in Arizona is an amazing natural feature. It is so majestic and immense, yet it was carved simply: by water. Kids will be amazed to learn that, given enough time and enough flow, water can carve deeply into the Earth. This book will look at how water erodes stone, and how different stones wear away at different rates. The results are some of natures most beautiful landforms.
