A landform is a natural or anthropogenic [1] [2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain , and their arrangement in the landscape is known as topography .
Fluvial landforms of streams; Fluvial terrace – Elongated terraces that flank the sides of floodplains and river valleys; Canyon – Deep chasm between cliffs (Gorge) Gully – Landform created by running water and/or mass movement eroding sharply into soil; Island – Piece of subcontinental land surrounded by water; Levee § Natural levees
Gully – Landform created by running water and/or mass movement eroding sharply into soil; Guyot – Isolated, flat-topped underwater volcano mountain; Hanging valley – A tributary valley that meets the main valley above the valley floor; Headland – Landform extending into a body of water, often with significant height and drop
In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp". The tread and the steeper descending slope (riser or scarp) together constitute the terrace.
In 1921, A.K. Lobeck published A Physiographic Diagram of the United States, using an advanced version of the hill profile technique to illustrate the distribution of landforms on a small-scale map. [1] Erwin Raisz further developed, standardized, and taught this technique, which uses generalized texture to imitate landform shapes over a large ...
In the diagram top right, the saddle is comparable to the leftmost drawn type. A saddle is the lowest area between two highlands ( prominences or peaks) which has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, and, so is concurrently the local highpoint of the land surface which falls ...
A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map ...
