What's So Hot About Volcanoes

Don't wait for a trip to the thermal pools of Iceland or the black beaches of Hawaii to discover what's so hot about volcanoes. Warm up with a copy of this book. Lively discussions introduce readers of all ages to the creative power of volcanoes, explaining the reasons behind where they form, what they look like, and when they explode. Think of a volcvanoe as the safety valve on a pressure cooker, author Wendell Duffield tells readers. The inside of Earth reaches a blistering 9,000 to 11,000 degress Fahrenheit, and volcanoes simply release some of that pent-up heat from time to time. Some volcanoes erupt so gently that observers can stand nearby while others erupt so violintly that they distroy themselves, as well as everything within reach of their hot gases, lava, and ash. Sections explore the challenges of predicting eruptions, what happens when magma mixes with water, and how people are using volcanic hear for energy.
