Soft matter physics of the ground beneath our feet.

Inspired by presentations by the authors during a workshop organized at the Princeton Center for Theoretical Science (PCTS) in January 2022, we present a perspective on some of the outstanding questions related to the"physics of the ground beneath our feet."These identified challenges are intrinsically shared with the field of Soft Matter but also have unique aspects when the natural environment is studied.
