Developed with extensive community involvement and support from the US National Science Foundation, it is about our planet’s dynamic surface, a place where Earth and atmosphere meet and life thrives.Key Concepts in Geomorphology takes an integrative science approach that applies principles of physics, chemistry, biology, and mathematics in the understanding of Earth surface processes and the evolution of topography over short and long timescales to solve problems important to people and societies. The authors also hone in on practical applications, showing how scientists are using geomorphological research to tackle critical societal issues (natural disaster response, safer infrastructure, protecting species, and more).
