Rainy days might make some people sad, and while we might not want to get caught in a downpour, our Earth needs rain. Rain is responsible for keeping our plants healthy, giving us drinking water, and giving us a way to cool off when it’s hot. Your readers will learn each step of the water cycle, why it is one of Earth’s most important processes, and the role that rain plays in it. Photographs and a simple diagram depict the water cycle in action. Reading this book will give young learners a new appreciation for rainy days.
