This series investigates the world above and below the surface of the seas and oceans, explaining how they were formed, why they are constantly in motion, their importance as a source of food, minerals and energy, and the latest developments in underwater exploration. Also described are some of the thousands of fascinating marine plants and animals and the urgent need for international co-operation in finding ways to protect them from the devastating effects of overfishing and pollution. Describes the story of the oceans - their formation, the continual changes that are taking place, and the physical features and resources to be found on the ocean floor. For hundreds of years people believed the ocean floor to be flat, but in fact the landscape is as varied as that on land, with mountain ranges, deep trenches, volcanoes and vast plains. This book shows how the oceans were first formed and how they are constantly changing because of plate movements and volcanic activity in the Earth's crust. It also describes features to be found on the floors of the Atlantic, Pacific, Indian and Arctic Oceans, and the gas, oil and other minerals that are extracted from the sea-bed.
