One spread is devoted to every month, with full-color illustrations and diagrams accompanying explanations of the relationship between the sun and the earth. The problem begins on page one: "Seasons are caused as the earth travels around the sun; as the position of the earth's surface changesmoving either closer to or away from the sunthe seasons change. . . . As the earth revolves, weather conditions change periodically. These changes cause the seasons." The text never becomes much clearer than that ("the movement of stars is caused by the earth's rotation"), and the tour through the months focuses more or less on a strict four-season model, in which January is frigid and snowy and by March spring is in sight. The book concludes with a glossary that has its own flaws, e.g., perennial plants are "plants that keep their leaves all year round."
