Why oh why are deserts dry?

In this latest installation of the Cat in the Hat's Learning Library, the Cat takes Sally and Dick to explore different kinds of deserts around the world, from the hot, dry Sonoran and Mojavi to the bitter cold Gobi and Antarctica. Young readers learn why deserts are dry, and how plants and animals—including cactus, kangaroos, camels, penguins, roadrunners, and many others—have adapted to survive the unforgiving climate. Also included: how sand dunes are formed; the reason we see mirages, and how shallow water beneath the surface of the ground can create an oasis. Fans of the new PBS preschool science show The Cat in the Hat Knows a Lot About That! (which is based on the Learning Library series) won't want to miss this hot new addition to the series!
