Erosion, Deposition, and Weathering Across the Solar System is the fourth volume of the Comparative Planetology series. The book summarizes erosional landforms across the Solar System, with an emphasis on the mechanistic processes responsible for these features, including case studies and methods of data and image analysis. Using comparative studies of planetary bodies and various Earth locations as natural laboratories to test models of erosive processes and landscape evolution, the book provides a current review of understanding of the evolution of planetary surfaces for Earth and those of our Solar System. planetary surfaces images across the Solar System reveal the ubiquity of erosional processes on planets, moons, and other bodies. From branching valley networks on Mars to hydrocarbon rivers on Titan to nitrogen glaciers on Pluto, landforms across the Solar System are conspicuously similar to features that we are familiar with on Earth. This familiarity suggests similar erosional processes are occurring across the Solar System despite drastically different surface conditions and material properties. Erosion, Deposition, and Weathering Across the Solar System serves as an accessible reference for both established Earth scientists interesting in applying their expertise to extraterrestrial problems, as well as those who are just beginning to immerse themselves in the field of planetary science or require comparative planetology information beyond their body of expertise.
