Climb aboard the earth for the adventure of a lifetime! As you travel, watch shadows move from here to there as day stretches into night, and feel the weather change as one season rolls into the next. All these amazing things happen because the earth is constantly in motion. Spinning and circling, gliding and tilting, as passengers of the earth, our voyage never ends! With poetic text and gorgeous illustrations, G. Brian Karas illuminates our earth and its cycles and does a brilliant job of making the concepts of rotation and revolution understandable to even the youngest readers.
