TerrainTerrain (from Latin'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of a 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. Over a large area, it can affect weather and climate patterns.
GeomorphometryGeomorphometry, or geomorphometrics (Ancient Greek: γῆ, romanized: gê, lit.'earth' + Ancient Greek: μορφή, romanized: morphḗ, lit.'form, shape' + Ancient Greek: μέτρον, romanized: métron, lit.'measure'), is the science and practice of measuring the characteristics of terrain, the shape of the surface of the Earth, and the effects of this surface form on human and natural geography.
ElevationThe elevation of a geographiclocation is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotentialgravitationalsurface (see Geodetic datum § Vertical datum).
United States Geological SurveyThe United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the United States Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes.
LandformA landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography.Quadrangle (geography)A quadrangle (or quad) is a region of the Earth's surface bounded by two parallels (circles of constant latitude) and two meridians (lines of constant longitude). The term is especially associated with topographic maps produced by the United States Geological Survey (USGS) of quadrangles covering the United States. Quadrangle maps are usually named after local physiographic features; for example, "the Ranger Creek, Texas quad".
DepictionDepiction is reference conveyed through pictures. A picture refers to its object through a non-linguistic two-dimensional scheme, and is distinct from writing or notation. A depictive two-dimensional scheme is called a picture plane and may be constructed according to descriptive geometry, where they are usually divided between projections (orthogonal and various oblique angles) and perspectives (according to number of vanishing points).
Planetary sciencePlanetary science (or more rarely, planetology) is the scientific study of celestial bodies (such as planets (including Earth), moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation. It studies objects ranging in sizes from micrometeoroids to huge gas giants, with the aim of determining their composition, dynamics, formation, interrelations and history.
Natural environmentLand management has preserved the natural characteristics of Hopetoun Falls, Australia while allowing ample access for visitors.An image of the Sahara Desert from satellite. It is the world's largest hot desert and third-largest desert after the polar deserts.The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth.
CultureSocial behavior and norms of a societySymbolic expression developed as prehistoric humans reached behavioral modernityReligion and expressive art are important aspects of human culture.Germans marching during a folk culture celebrationThe Acropolis of AthensWritings often create a sense of cultural identity, Ernest Hemingway writing.Culture ( or ) is a concept that encompasses the social behavior, institutions, and norms found in human societies, as well as the knowledge, beliefs, arts, laws, customs, capabilities, attitudes, and habits of the individuals in these groups.
Earth scienceEarth science or geoscience includes all fields of natural science related to planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere, hydrosphere/cryosphere, atmosphere, and geosphere (or lithosphere). Earth science can be generalized into planetary science, a more recent branch of science.*As an Amazon Associate I earn from qualifying purchases.
