A wall of water that can be more than 100 feet (30.5 m) tall may sound unimaginable, but tsunamis are among the strongest and most destructive of Earth’s natural events, making them critical for young learners to understand. This book offers key facts about how tsunamis form, where they form, and what some of the deadliest past tsunamis have taught people about preparing for these natural disasters. This volume also includes colorful images, compelling sidebars, graphic organizers, and text that is carefully written to be accessible to young readers.
