Landforms created by running water dominate the land surface of earth. However, although the role of water is seen everywhere, it is seen at its best in those regions where the climates are wet enough to support a forest vegetation with a continuous canopy. The seasonal fluctuations in the character of precipitation with snow in winter and rain in summer which characterize cool temperate forest climates and the legacies of recent past cold periods in high latitudes means that the landforms of the humid tropics should be regarded as the "normal" or "type" features due to erosion by running water.This discussion of humid landforms, together with J. A. Mabbutt's volume "Desert Landforms" completes a series of seven volumes on systematic geomorphology. It attempts to break with traditional approaches and to discuss humid landforms from the standpoint of the humid tropics. In addition, it seeks to demonstrate that the processes creating and destroying landforms are also those that regulate biotic activity at the earth's surface. The approach followed in this book is to describe the processes affecting the evolution of landforms in terms of the circulations of energy, water and materials before introducing the complication of legacies of different ages from the past. Theories of landform evolution are briefly reviewed in the final chapter.

Geomorphology can be defined simply as the study of landforms. Landforms are the result of the interaction between what Ritter (1978) has called the driving and resisting forces. The driving forces or processes are the methods by which energy is exerted on earth materials and include both surface, geomorphological or exogenous processes and subsurface, geological or endogenous processes. The resisting forces are the surface materials with their inherent resistances determined by a complex combination of rock properties. Stated in these simple terms it would be expected that both sides of the equation be given equal weight in syntheses of landform evolution. However, this has not been the case. Until about the 1950s, geomorphology was mainly descriptive and concerned with producing time-dependent models of landscape evolution. Although the form of the land was the main focus, there was little detailed mention of process and scant attention to the properties of surface materials. There were, of course, exceptions. In the late 19th century G.K. Gilbert was stressing the equilibrium between landforms and processes. Many hydrologists were examining the detailed workings of river 'systems and drainage basins, culminating in the classic paper of Horton (1945).

Physical Geography Made Simple focuses on developments in physical geography, including advancements in the study of landforms, weather, climate, water, soils, plants, and animals. The book first offers information on rocks and relief, weathering, slopes, and rivers and drainage basins. Topics include rock structures and landforms, crustal structure and movement, physical and chemical weathering, measurement and description of slopes, and transport, erosion, and deposition. The manuscript then ponders on glacial and periglacial landforms and desert and uropical landforms. The publication takes a look at coastal features, landscape development, and the atmosphere and its energy. The manuscript also elaborates on moisture in the atmosphere, air motion, general circulation, and weather. Discussions focus on fronts, weather prediction, planetary wind belts, pressure variations, upper air motion, adiabatic processes, and evaporation and condensation. The text is a valuable reference for geographers and readers interested in physical geography.

This introductory text details the land surface of the earth in a readable style covering the major issues, key themes and sensitivities of the environments/landscape. Emphasizing the major ideas and their development, each chapter includes case studies and details of influential scientists (not necessarily geomorphologists) who have contributed to the progress of understanding. Providing a very clear explanation of the understanding achieved and of the debates that have arisen, the book is comprised of 12 chapters in four sections: Visualizing the land surface explains and explores the composition of the land surface and outlines how it has been studied Dynamics of the land surface considers the dynamics affecting the earth’s land surface including its influences, processes and the changes that have occurred Environments of the land surface looks to understand the land surface in major world regions highlighting differences between the areas Management of the land surface is an examination of the current and future prospects of the management of the earth’s land surface

This book provides an authoritative review of the resources of soils, water, climate, forests and pastures on which agriculture depends. It assesses the interactions between land resources and wider aspects of development, including population and poverty. Unless action is taken, the developing world will face recurrent problems of food security and conflict. The book gives some forcefully-expressed criticisms of current methods of assessing land degradation and placing an economic value on land. It should be read by all involved in rural development, including scientists, economists, geographers, sociologists, planners, and students of development studies. It provides a summary and perspective of the field of land resources, and suggests improvements needed to conserve resources for future generations. The hardback edition of the book received excellent reviews.
