This seven-book series is a user’s guide to locating Earth’s continents and the countries of the world. Kids will learn that more than 200 million years ago, all continents began as part of Pangaea, a supercontinent that broke up to form seven continents. They will acquire map-reading skills by learning the directions in which longitude and latitude lines point, where the equator is, and what the prime meridian is. The final chapter in each book features a scientist, related to the continent, with specialties that range from dinosaurs to the study of volcanoes.
