Hot air rises and cold air sinks so winds move between the equator and the polar regions. The work of the wind on the water is predictable. The Great Pacific Garbage Patch is a testament to both the movement of Earth’s winds and the effect of humans on the Earth. In this chapter, students will begin by modeling wind movements and then read about the resulting Garbage Patch. They will also examine from a map how the hot and cold currents affect global weather. The reading strategy featured here is “identifying text signals for cause and effect.” 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.
