This dynamic site from National Geographic Education features invigorating ganders into four of nature’s most devastating forces. Start with Tornadoes. Six sections – What is a Tornado, What Causes Tornadoes, and Characteristics of Tornadoes, among others – provide an informative overview of these sudden, sometimes devastating wind events. Next, take a look at Volcanoes, and click on headings like Where Do Volcanoes Occur? and How Do Volcanoes Erupt? Hurricanes and Earthquakes each deserve careful attention, especially the interactive, Spin Off Your Own Hurricane, where you can learn how hurricanes are made by building one yourself.
