All around the world, from icy wastes to tropical rain forests, there are lakes of different shapes and sizes. In this book the reader journeys to the ten biggest lakes in the world. Lakes physical features are explained with a full page spread of a world map indicating the major lakes. The Caspian sea is the largest and possibly the oldest lake in the world. Many rivers flow into this huge salt-water lake but no river runs out of it. Lake Superior is the biggest and deepest of the five Great lakes of North America and is the largest freshwater lake in the world. The lakes are then described in descending order of size. Lake Victoria (the largest lake in Africa); Lake Huron the second largest of the Great Lakes, Lake Michigan; the Aral Sea, next in order, which lies east of the Caspian Sea is shrinking because water from the rivers that feed the lake has been diverted into man-made canals. Lake Tanganika lies at the lower end of East Africa's Great Rift Valley and is home to hippopotamuses, crocodiles and large numbers of water birds. Great Bear Lake is fed by melting snow and is famous for fishing. Just north of Mongolia is Lake Baikal which lies in south-eastern Russia. In the East African Country of Malawi, is Lake Malawi which is fed by 14 rivers and flows to the Indian Ocean.
