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.

Alpine permafrost (most permafrost is located in high latitudes (i.e. land in close proximity to the North and South poles)) may exist at high altitudes in much lower latitudes. |
|||
Cliff is a significant vertical, or near vertical, rock exposure. Cliffs are formed as erosion landforms due to the processes of erosion and weathering that produce them. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. |
|||
Escarpment is a steep slope or long cliff that results from erosion or faulting and separates two relatively level areas of differing elevations. |
Foothills are geographically defined as gradual increases in hilly areas at the base of a mountain range. They are a transition zone between plains and low relief hills to the adjacent topographically high mountains. |
||
Glacial erratic is a piece of rock that differs from the size and type of rock native to the area in which it rests. |
Glaciation is a glacial period is an interval of time within an ice age that is marked by colder temperatures and glacier advances. (Columbia Icefields, Alberta Canada) |
Glacial lake is a lake with origins in a melted glacier. |
|
Hanging Valley: a valley eroded by a small tributary glacier, such that the elevation of the valley floor is higher than the elevation of the valley floor that the hanging valley joins. The erosive power of glaciers is dictated by their size: the larger a glacier, the farther down into the landscape it can erode. |

Physical weathering is the disintegration of earth material without undergoing a chemical change. Physical weathering results in increased surface area for chemical reactions to occur on. |
Wind scoop Hollow around rock outcrop caused by wind erosion or enhanced ablation. |
Tree line or timberline is the edge of the habitat at which trees are capable of growing. Beyond the tree line, they are unable to grow because of inappropriate environmental conditions (usually cold temperatures, insufficient air pressure, or lack of moisture). |
