Scotland is justly famed for its magnificent scenery - mountains, lochs, islands, wild rocky places and sandy beaches. All this is evidence of an exciting geological history which began 3,500 billion years ago and is still continuing. The sheer diversity of Scotland's rocks and landforms are the physical reminders of a fascinating journey through time. They reveal that the land that makes up Scotland today has travelled the world and has not always even belonged to one single continental landmass. At different times, too, continents formed and split apart, ancient volcanoes erupted vast quantities of lava and Ice Age glaciers shaped the landscape. Containing a huge amount of detailed information presented in clear, comprehensible language and enhanced throughtout with specially commissioned illustrations, diagrams and photographs, this is an essential book for anyone interested in the world around them.
