This is a layperson's guide to why the scenery in Britain is so varied. It starts in the far north-west of Scotland, describing and explaining the oldest rocks in the British Isles. It then explains the concept of geological time before starting a backwards journey from the most recent past. The geology of each period is explained with reference to its effects on the landscape we see around us and how the rocks were formed. There is a map with each chapter showing where rocks of the period being discussed are at the surface.The book is written in a friendly and accessible style, with enough use of anecdote and humour to make it an enjoyable and relatively light read, while still being informative.There are suggestions for further reading in the back for anyone who wants to go into the geology in more detail. I enjoyed reading it even though (in theory) I should already know most of what it says. I would recommend this to anyone with an interest in landscapes.
