land surface
Terrain above water
The land surface is the outer boundary of Earth's solid ground—where soil, rock, vegetation, and human structures meet the atmosphere.
The term appears in scientific and technical contexts: Climate models must account for how the land surface absorbs and reflects solar radiation.
It distinguishes terrestrial areas from water surfaces and subsurface layers.
