Whereas hydrologists are mostly concerned with the movement of water, a common task is to assess the impact of water flow on the transport of materials – sediment and solutes.

Nearly all major planets and moons in our Solar System have been visited by spacecraft and the data they have returned has revealed the incredible diversity of planetary surfaces. Featuring a wealth of images, this textbook explores the geological evolution of the planets and moons. Introductory chapters discuss how information gathered from spacecraft is used to unravel the geological complexities of our Solar System. Subsequent chapters focus on current understandings of planetary systems. The textbook shows how planetary images and remote sensing data are analyzed through the application of fundamental geological principles. It draws on results from spacecraft sent throughout the Solar System by NASA and other space agencies. Aimed at undergraduate students in planetary geology, geoscience, astronomy and solar system science, it highlights the differences and similarities of the surfaces at a level that can be readily understood by non-specialists. The new fourth edition of Fundamentals of Geomorphology continues to provide a comprehensive introduction to the subject by discussing the latest developments in the field, as well as covering the basics of Earth surface forms and processes.The revised edition has an improved logically cohesive structure, added recent material on Quaternary environments and landscapes, landscape evolution and tectonics, as well as updated information in fast-changing areas such as the application of dating techniques, digital terrain modelling, historical contingency, preglacial landforms, neocatastrophism, and biogeomorphology. The book begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss:Endogenic processes: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints. Exogenic processes: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea landforms developed on limestone and long-term geomorphology, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change.Featuring over 400 illustrations, diagrams, and tables, Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, and providing guides to further reading, chapter summaries, and an extensive glossary of key terms, this is an indispensable undergraduate level textbook for students of physical geography.
