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 .
Topographic maps are also commonly called contour maps or topo maps. In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are often called or quads or quadrangles. Topographic maps conventionally show topography, or land contours, by means of contour lines.
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 ...
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 ...
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.
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]
Oceanic trenches are long, narrow topographic depressions of the seabed. They are the deepest parts of the ocean floor, and they define one of the most important natural boundaries on the Earth's solid surface: the one between two lithospheric plates. Trenches are a distinctive morphological feature of plate boundaries. Trenches are found in ...
USGS topographic map of Stowe, Vermont with contour lines at 20-foot intervals. Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed.
