The interface between the solid Earth and its outer layer composed of the atmosphere, hydrosphere, and biosphere hosts crucial mechanical and chemical processes. These processes drive erosion, sediment transport, and deposition, responsible for mass redistribution across the Earth's surface. In this presentation, we first review how the coupling between the solid Earth and surface processes can be modeled and implemented inside 2-D and 3-D long-term geodynamics models. We then delve into the feedback between tectonics and surface processes that shape the Earth's landscape. Through examples drawn from both 2-D and 3-D geodynamic models, we demonstrate how surface processes, from the scale of a fault to larger basin or mountain scales, influence tectonic behavior and reciprocally how tectonics and isostasy influence the landscape evolution.
