具體描述
For anyone curious about the geological history of our country, "Canada Rocks" is a marvelous portrait of what the authors describe as the incredible 4 billion year 'construction project' that gave shape to the continents, mountains, and oceans of planet Earth, and created the world's second largest country - Canada. Profusely illustrated throughout with full colour and black and white photographs, charts, maps, graphs and sketches, the book explores the country from north to south, and from east to west, exploring that incredible history through modern day sites and land shapes created in our distant past. Read about: Rocks in Point Pleasant Park in Halifax were once part of Morocco, left behind when the Atlantic Ocean came into being. Canada's Arctic regions were formerly part of what today is Siberia. Greenland was once a part of Labrador. Fossils in a road cut in Cache Creek, British Columbia once lived in a sea that covered China. The violent collisions of continents and other land masses, the growth and decay of enormous mountain ranges, the impact of meteorites, and the comings and goings of vast ice sheets are explored in fascinating detail, as is the creation of our rocky resources from coal to diamonds. An essential reference for students and anyone fascinated with the geological forces that created our country, the book includes a great many sites that can be visited for close-up study, making it an invaluable field guide for exploring our history and the world around us.
