Earth is a place of great physical and cultural diversity, yet people know little about it. Physical geography deals with the spatial and temporal characteristics and relationships of all phenomena within the physical environment. A systematic study of physical geography is of immense help in understanding the numerous environmental challenges of the contemporary period. The book is aimed to explain the spatial dimensions of the earth’s natural systems and their processes. Thoroughly revised with three new chapters and over eighty new maps and diagrams, this updated fifth edition of bestselling introductory textbook is well suited to the curriculum of established physical geography courses. The text includes many special features that are intended to enhance and clarify students’ understanding and mastery of the subject. Throughout, the scientific ideas and processes are explained in a simple manner supported by a range of illustrative material including maps, diagrams and photographs.
