A topographic map of Stowe, Vermont with contour lines This false-color satellite image illustrates topography of the urban core of the New York metropolitan area, with Manhattan at its center. Topography is the study of the forms and features of land surfaces .
Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...
Gully – Landform created by running water and/or mass movement eroding sharply into soil; Hill – Landform that extends above the surrounding terrain; Hillock, also known as Knoll – Small hill; Mesa – Elevated area of land with a flat top and sides, usually much wider than buttes; Mountain pass – Route through a mountain range or over ...
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.
A landform 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. Landforms are categorized by features such as elevation, slope, orientation, stratification, rock exposure, and soil type.
A topographic map of Ngorongoro Crater in northern Tanzania, the world's largest inactive, intact, and unfilled volcanic caldera, which formed when an immense volcano erupted and collapsed on itself 2–3 million years ago. The floor of the caldera is 600 metres (2,000 ft) below its rim and covers more than 260 square kilometres (100 sq mi).
Badlands incised into shale at the foot of the North Caineville Plateau, Utah, within the pass carved by the Fremont River and known as the Blue Gate. G. K. Gilbert studied the landscapes of this area in great detail, forming the observational foundation for many of his studies on geomorphology. [1]
