This textbook for the first year university studies gives a comprehensive review of geomorphology. It stresses the importance of the theory of tectonic and climatic changes on a global scale and so takes account of the two revolutions which are occurring in the Earth Sciences at the present time. The book has three main parts. In the first, global tectonics is used as the framework for discussion of the Earth's major relief features, their development and structure, and the landforms resulting from tectonism. The second part is concerned with the nature of geomorphic resistance and of the processes of weathering, erosion and deposition. In the final part the significance of and evidence for, climatic change and long-term evolution of landforms are discussed, and the evidence for the impact of climate and climatic change upon the major bioclimatic zones of the continents is reviewed. The clear and straghtforward style, together with the liberal number of illustrations, should make the material accessible to all students who wish to have an understanding of landforms through an analysis of their relation to structural, tectonic and earth surface processes.
