This book describes the formation of igneous rocks by crystallisation from a molten liquid (magma) and the formation of metamorphic rocks under high temperatures and pressures. It also looks at the deformation of rocks by folding and faulting during crustal movements and mountain building, including information and evidence that may be obtained from geological maps. Activities on DVD-ROM enable you to explore the effects of folding and faulting in 3-D, and a simple virtual field trip investigates the effects of an igneous intrusion upon surrounding rocks. Unfortunately due to copyright restrictions some of the DVD material refered to in this book is not available for sale as a result study of some of the activities may be limited.
