Volcanoes and avalanches are extreme natural events on opposite ends of the temperature spectrum -- volcanoes cause destruction with hot lava, while avalanches do their damage with ice and snow. With the help of text that's broken down into manageable sections and visual elements such as graphic organizers and diagrams, readers enhance their understanding of the science behind volcanic eruptions and avalanches. Specific case studies emphasize the way humans are impacted by these disasters, and maps highlight areas where infamous disasters have occurred. The eye-catching design makes use of both illustrations and vivid photographs to keep readers engaged as they learn.
