Our Baffling Planet is a series of early reader books for ages 5 to 7. They are science based, teaching kids about the water cycle, plant life cycle, and rock cycle. David the Rock teaches children about the different layers of the Earth, erosion, weathering, lithification, tectonic plates, convergent and divergent currents, transformation, and the three different kinds of rocks - igneous, sedimentary, and metamorphic. The book also touches on minerals and elements, how rocks are made, and what we use rocks for everyday!
