Rocks may seem big and bulky, but they are in a constant cycle of change. Readers learn about the cycle rocks undergo to change from one kind into another as well as the factors that play a role in the process, such as heat, pressure, and weathering. As they uncover each part of the process, readers are entertained and informed and simultaneously able to further their learning of this important cycle outside of the classroom! Eye-catching graphics, diagrams, and age-appropriate texts combine to make a reading experience that is sure to fascinate readers.
