The Sun is the ultimate power source for many of the processes on Earth, and water serves as a battery, storing and releasing the Sun’s power. These ideas are important for students to understand, because they form the basis of weather. In this chapter, students will discover how the power of the Sun and the heat capacity of water produce wind and hurricanes. The reading strategy featured here is “identifying text signals for comparisons and contrasts.” A materials list, teacher background information, references, assessment, and outcomes are provided. This book selection includes the Table of Contents, Acknowledgments, About the Author, Image Credits, and Index.
