The Geomorphology of the Human Age

Abstract The Earth's surface morphology is a consequence of dominant forcing such as tectonic uplift, erosion, sediment transport, and climate. Recently, the Earth science community also started to consider biota as a geomorphological agent that has a role in shaping the Earth surface, even if at a different scale and magnitude than that of other major forcings. Human activities directly or indirectly move large quantities of soil, which leave clear topographic signatures on the Earth's morphology. These signatures have the capability to affect Earth surface processes. This article provides an overview of the role of humans as a geological agent in shaping the morphology of the Earth. We consider agricultural landscapes, mining activities, and road networks. We provide examples in different regions of the world. The final section considers concluding observations and open challenges, where we focus on future challenges, related to Anthropocene, in the Earth science community.
