Some are peaceful. Some are powerful. Some are modest, while others are majestic. Rivers play a vital role in the life of our planet. They provide water for wildlife, plantlife, and people. Some rivers are watery highways for big boats carrying goods to market. But how were rivers made? David L. Harrison and Cheryl Nathan take readers on a journey down a river, from its source at the top of a mountain, to its mouth where it meets the sea. Along the way, they show how nature created the river and how the river works within the world around us. Through crystal-clear text and lively illustrations, young readers will discover why rivers are nature’s wondrous waterways.
