Terrain (from Latin: terra 'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution.
Summit – Point on a surface with a higher elevation than all immediately adjacent points; Trim line – Clear line on the side of a valley marking the most recent highest extent of the glacier; Truncated spur – Ridge that descends towards a valley floor or coastline that is cut short; Tunnel valley – Glacial-formed geographic feature
Transverse – intersecting at any angle, i.e. not parallel. Orthogonal (or perpendicular) – at a right angle (at the point of intersection). Elevation – along a curve from a point on the horizon to the zenith, directly overhead. Depression – along a curve from a point on the horizon to the nadir, directly below.
α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A larger number ...
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.
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 peak of hurricane season is approaching this weekend. It’s crucial to know what terms meteorologists might use and what they mean.
2. A type of point bar consisting of a low, narrow ridge running in line with the curve of a meander, formed when the river overflows its banks. [4] sea 1. Any large body of salt water surrounded in whole or in part by land. 2. Any large subdivision of the World Ocean.
