A Makhtesh is a geological landform considered unique to the Negev desert of Israel. A cirque may also be a similarly shaped landform arising from fluvial erosion. The plant takes advantage of the natural steep sand dune landform of eastern Lake Michigan. The Australian continental landmass consists of six distinct landform divisions. The Lendu Plateau clawed frog is endemic to that landform in the ecoregion. A petroglyph that represents a landform or the surrounding terrain is known as a geocontourglyph. A hill is a landform that extends above the surrounding terrain. A raised beach is an emergent coastal landform. Dunes are a dominant landform on Titan. The current is strongly constrained by landform and bathymetric features. Lake levels rose while the Wizard Island landform inside the crater was forming. The valley is contained in the Las Vegas Valley landform. Each landform has its own range of habitats. Sometimes this occurs seaward of a trough (marine landform). Blacktail Butte is a prominent landform rising from the valley floor.
