A saddle can vary from a sharp, narrow gap to a broad, comfortable, sway-backed, shallow valley so long as it is both the high point in the sloping faces which descends to lower elevations and the low area between the two (or three or four. [a]) flanking summits. Concurrently, along a different axis, it is the low point between two peaks, so as ...
In general usage, a cuesta is a hill or ridge with a gentle slope (backslope) on one side, and a steep slope (frontslope) on the other. The word is from Spanish: "flank or slope of a hill; hill, mount, sloping ground". In geology and geomorphology, cuesta refers specifically to an asymmetric ridge with a long and gentle backslope called a dip ...
Coral reef – Outcrop of rock in the sea formed by the growth and deposit of stony coral skeletons; Cove – Small sheltered bay or coastal inlet; Cuspate foreland – Geographical features found on coastlines and lakeshores; Dune system – Hill of loose sand built by aeolian processes or the flow of water
During most of the 20th century three models of hillslope evolution were widely diffused: slope decline, slope replacement and parallel slope retreat. Until the 1950s models of hillslope form evolution were central in geomorphology. The modern understanding is that the evolution of slopes is much more complex than the classical models of ...
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 ...
The letters A and B at the top correspond to the line labeled A--B on the smaller map. In this example, the vertical scale is exaggerated compared to the horizontal scale. A cross section or cross-section , in geology , is a diagram representing the geologic features intersecting a vertical plane , and is used to illustrate an area's structure ...

Generally, they are elongated, oval-shaped hills, with a long axis parallel to the orientation of ice flow and with an up-ice (stoss) face that is generally steeper than the down-ice (lee) face. [7] Drumlins are typically between 250 and 1,000 m (820 and 3,280 ft) long and between 120 and 300 m (390 and 980 ft) wide. [8]
