Earthly phenomena in all their glory shine from the pages of this oversized celebration.Smith's first title in this series, Glow (2023), shone a spotlight on luminescent animals; in this vibrant introduction to earth science, she explores everything from the planet's structure to geology-related myths and legends. A science illustrator by training, Smith aims to inspire a sense of wonder in readers; to that end, she fills her pages with spectacular artwork and intriguing examples. She begins by defining the word phenomenon and goes on to examine volcanoes, geologic layers, mountains, earthquakes, geysers, caves, glaciers, hydrothermal vents, auroras, clouds, storms, light, and even careers in geoscience. Each color-filled spread focuses on a single topic, with short explanations and, often, an image with carefully labeled examples. The text, set in a relatively small font and filled with appropriate but perhaps unfamiliar terms, may challenge young readers, but the imagery is striking. Neon colors grab readers' attention. Smith fills many of her images with tiny dots, which adds depth and shading and also hints at the atoms within. The humans who appear are racially diverse. Though the book lacks notes, a bibliography, or suggestions for further reading, it includes a useful glossary and index.A work brimming with natural marvels, sure to entrance burgeoning geologists.
