A rock's chemical or physical makeup may change because of conditions such as temperature, stress, or pressure.

Full-color photographs depict these rocks in nature. A helpful graphic organizer shows how these fascinating rocks form.

Young terrestrial explorers are introduced to different types of rocks, where in the cycle these rocks fit, and where in Earth's layers each step takes place. Fact boxes provide readers with fun additional information. A diagram helps readers make sense of the new information they're learning.
