The Earth is round like a ball and it moves in circular motions. It changes in patterns that go round and round like the wheels of a bike. So begins EARTH CYCLES, a book that describes three of the cyclical phenomena created by the movement of Earth. Day to night to day and back again is one cycle, and the cycle of the moon gradually moving from a sliver to a giant disk and back again is another. The seasons’ never-ending cycle of spring to summer to fall to winter to spring again is the third. The book offers the scientific reason behind each of the cycles while at the same time providing an overview of the wondrous order of our planet.

About the Authors

Michael Elsohn Ross is the author of more than forty books for children, most about science or world cultures. He lives right next to California's Yosemite National Park, where, for close to thirty years, he has been working as a naturalist, taking visitors on hikes and walks to learn all about the park. His ideas, he says, "come from my work as a naturalist and my adventures with school kids."

Gustav Moore grew up on a farm in Whitefield, Maine, and graduated from Rochester Institute of Technology with a degree in illustration. He has illustrated eight children's books. He lives in Portland, Maine.
