These can range from less than one meter to tens of meters in width and depth and from a few meters to more than a kilometer in length. Cornices can present serious hazards to mountain travelers including climbers, skiers, hikers, and snowmobilers.

Landform or physical feature comprises a geomorphological unit, and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such, is typically an element of topography.

Landform elements also include seascape and oceanic waterbody interface features such as bays, peninsulas, seas and so forth, including sub-aqueous terrain features such as submersed mountain ranges, volcanoes, and the great ocean basins.
