Unearthing igneous rocks

Igneous rocks form when molten rock cools and hardens. Readers will learn how differences in composition and cooling form different types of igneous rocks. Chapters include graphic organizers to help explain topics such as mountain formation, volcanoes, and how igneous rocks fit into the larger rock cycle. 

 The interactive eBook version of this book includes high-interest information that expands on the topics covered in the print version. These additional photographs, videos, and graphic organizers provided an enriched experience of the book.
