Dynamic topography is surface or internal-boundary relief supported by stresses from interior flow. Inferring it requires separating effects of the thickness of the crust, thermal subsidence and other loads, and depends on the assumed interior viscosity and density structure.

Dynamic topography refers to the variation in the Earth's surface elevation due to dynamic processes occurring beneath the crust, primarily influenced by mantle convection and tectonic activity. Unlike static topography, which is determined by features such as mountains, valleys, and plateaus formed through geological processes like erosion and sediment deposition, dynamic topography changes over geological timescales because of movements within the Earth's mantle.
