Hundred-mile winds and sky-high funnel clouds can mean only one thing: a tornado is coming. Readers will learn everything they need to know about tornadoes, from what they are and why and when they happen, to what remains after they rip through an area. Age-appropriate content thoroughly explains tornado activity in the United States and abroad, and real-life examples give readers insight into how communities cope with one of nature’s most destructive forces. The book includes fast facts about the biggest and most destructive tornadoes in history, and a section entitled "Survivors Speak" features survivors’ stories in their own words. Through stories about scientists and real-life storm chasers, readers will discover the fascination with tornadoes while also understanding the danger and destruction they bring. Stunning photographs and captions accompany the text, giving readers an eye-opening look at one of our world’s most incredible natural disasters.
