Since the division of geography into two distinct fields, human geography and physical geography, the number of geographical terms has rapidly increased. Covering all of the terms students of physical geography need to understand, this Penguin dictionary is one of the most comprehensive works of its kind, offering: * Over 5,000 entries * All the main terms used by modern physical geographers * Allied and associated topics such as botany and geology * Diagrams to complement the text * Meticulous cross-referencing to enhance understanding A companion Dictionary of Human Geography has been designed to complement this volume, and both dictionaries have been 'planned along similar lines, so that their formats are broadly comparable'.
