Floods are among the most common—and destructive—natural disasters. This accessible hi‑lo book explains how floods form, why heavy rain, snowmelt, storms, and broken dams can trigger them, and how they damage homes, roads, and communities. Readers explore flash floods, storm surges, erosion, and the dangers of contaminated water. The book also shows how scientists study flood zones, use satellites to track storms, and create maps that help predict future flooding. Clear text, engaging visuals, and critical‑thinking questions help developing teen readers understand how people prepare for floods and stay safe when waters rise.
