Continents on the Move

by: Jodi Wheeler-Toppen

Plate tectonics is the primary theory that drives explanation in geology, but the idea that land masses drift around the Earth can sound as crazy to students as it did to geologists in the early 1900s. Spending time on the history and evidence of plate movement can help students understand this pivotal idea. In this chapter, students will consider some of Alfred Wegener’s evidence for continental drift and read about what it took to challenge the prevailing views in geology. The reading strategy introduced here is “chunking.” It might be difficult to understand all of the ideas at one time, but if students break the sentence into chunks, they can think about each piece individually. 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.
