Eyewitness Science: Earth (Collins eyewitness science)

Science is all around and can be an endless source of discovery and wonder. Yet, for many people it conjures up thoughts of obscure laws and formulae. For them, this series of references should be practical and fun. From the outer limits of the Earth's atmosphere to the innermost core, this book looks in detail at the variety of materials and events that have shaped the planet. It follows the many theories and discoveries that have slowly built up into a picture of how land and the oceans have evolved, and examines in detail the many different rocks and landscape on the Earth. It also includes the dramatic effects of volcanoes and earthquake tremors, and looks at the great mystery of the Earth - the magnetic field.
