Other forms: landforms
Anything that's a geological part of the earth's surface, including mountains, peninsulas, and canyons, is a landform.
Landform is a good way to refer to natural features of Earth or any other planet or moon. A landform is defined by things including elevation, the type of soil or rocks, and slope. The moon's craters are landforms, and so are our planet's buttes, hills, ponds, and volcanoes. The movement of tectonic plates creates new landforms — and human activity, like surface mining, can erase old landforms.
