Book excerpt: How hot is molten lava? How are volcanoes formed? What happened with the volcano in Pompeii? Discover the answers to these questions and more, and learn about the inner workings of one of Earth's most terrifying natural phenomenon in Eye Wonder: Volcanoes. A precursor to DK's award-winning Eyewitness series, Eye Wonder was specially developed for children aged five plus, featuring astonishing photography exhibiting subjects within their natural setting offering a whole new level of information through powerful images. Vocabulary is accessible to young readers, with the meanings of new, subject-related words clearly explained. The combination of breathtaking visuals and informative, accurate text will hook even those children who usually avoid books. Reissued with a new jacket and eight new pages of mazes, look-and-finds, quizzes, and interactive activities, the new generation of Eye Wonder will capture readers' imaginations and give them a reason to delve even deeper into each book.
