This photographic book looks at igneous rock, one of the three main rock types. It explores how it is formed through the cooling and solidification of fiery orange magma or lava that explodes from volcanoes. This book covers important Earth science concepts and the different kinds of igneous rocks, how identify them by their physical properties, and what clues they offer about our planet's past. The text also clues readers in on the ways we can use this tough rock as a resource, and how people living near volcanoes can benefit from living in a volcanic environment. Sidebars, fact boxes, and interesting photos supplement the texts information-rich content.
