Another wonderful, pour-over-for-hours, book in the Explore the Earth series. The previous book, How the World Works, has a little cross-over with this new one, but there is plenty here to engage students in visual explanations of weather in all it's various forms. The piece-de-resistance, is a two-page spread of What is a Hurricane?, that simply and elegantly illustrates one of the most fascinating and dangerous elements of weather on earth. Humidity, high and low air pressure, jet streams, climates, climate changes and much more fill these pages of pop-ups, tab pulls, wheel turns and flaps to lift, with interesting facts and folklore about weather and how it affects us.
