Describes what tornadoes are, how they form, the scale used for classifying them, and what to do in case one approaches.
In her celebrated clear style, GAIL GIBBONS explores the power of tornadoes and explains what to do if one is coming your way. Tornadoes form when hot, humid air rises from the ground and meets with the cooler, denser air that is falling back to Earth. The two airstreams begin to swirl, pulling in more and more air to form a funnel-shaped cloud. The winds can swirl faster than 261 miles per hour! Using her praised combination of clear text and detailed illustrations, GAIL GIBBONS explains how tornadoes form, the scale used for classifying them, and the safest places to go in case one should happen near you.
GAIL GIBBONS has written and illustrated more than fifty books for Holiday House, including From Seed to Plant, The Moon Book, and Monarch Butterfly. She lives in Corinth, Vermont.
