zenith : The imaginary point on the celestial sphere that is directly above a particular location (i.e. in the vertical direction exactly opposite to the apparent direction of the gravitational force at that location). Contrast nadir.
zoning : The public regulation of land and building use to control the character of a place
yardang : A streamlined protuberance carved from bedrock or any consolidated or semi-consolidated material by the dual action of wind abrasion and erosion, especially one found in a desert.
world map : A map of most or all of the surface of the Earth.
World Geodetic System (WGS) : A standard geographic coordinate system, spheroidal reference ellipsoid (for raw altitude data), and geoid (which defines the nominal sea level) used in cartography, geodesy, and satellite navigation applications worldwide. The latest revision, WGS84, is the standard coordinate system used by the Global Positioning System.
world city : See global city.
windward : The side of a landmass facing the direction from which the wind is blowing. Contrast leeward.
wilderness : Any natural environment which has not been significantly developed or modified by human activity, or within which natural processes operate without human interference. Such areas are considered important for the survival of wild plant and animal species as well as for maintaining biodiversity and ecological stability. Wildernesses are often protected areas.
Western Hemisphere : The half sphere of the Earth that is west of the Prime Meridian and east of the antimeridian. It is opposite the Eastern Hemisphere.
weathering : The breaking of rocks into smaller rocks, gradually becoming soil.
wave-cut platform :
A flat erosion surface along the shore of a lake, bay, or sea that is formed by the undercutting and eventual collapse of a sea cliff as a result of repetitive wave action.
waterway : Any body of water that is deep, wide, and slow enough to be navigable by watercraft.
watershed : Another name for a drainage divide or drainage basin.
watercourse : Any channel followed by a flowing body of water such as a river or stream, potentially including channels that are dry for part or all of the year.
water table : The level below the land surface at which the subsurface material is fully saturated with water. The depth of the water table reflects the minimum level to which wells must be drilled for water extraction
water pollution : The contamination of water by chemical or biological constituents which make it unfit for use.
water mapping : A collection of data represented as a map showing different aspects related to water supplies.
water gap : A low point or opening in a ridge or mountain range carved by the erosional activity of flowing water and through which water continues to flow in the present day. Contrast wind gap.
wash : See arroyo.
wadi : 1. Another name for a valley, used primarily in Arabic-speaking parts of the world.
2. A dry, ephemeral riverbed which contains water only when heavy rainfall occurs.
volcano : A vent (opening) in the Earth’s surface through which magma erupts, or the landform that is constructed by eruptive material
volcanic crater : A type of crater created by volcanic activity, typically shaped like a bowl and containing one or more volcanic vents. Compare caldera.
volcanic avalanche:
A large, chaotic mass of soil, rock, and volcanic debris moving swiftly down the slopes of a volcano. Volcanic avalanches can also occur without an eruption due to an earthquake, heavy rainfall, or unstable soil, rock, and volcanic debris
village : A small, clustered human settlement or community, usually larger than a hamlet but smaller than a town and often in rural areas, though the criteria for distinguishing a village can vary considerably in different parts of the world.
viewshed : The geographical area that is visible from a particular location. It includes all surrounding points within line-of-sight of the location and excludes points beyond the horizon or obstructed by terrain and natural or artificial objects.
vent : An opening at the Earth’s surface through which volcanic materials (lava, tephra, and gases) erupt. Vents can be at a volcano‘s summit or on its slopes; they can be circular (craters) or linear (fissures)
vertical exaggeration : A scale used in certain maps, such as raised-relief maps, that deliberately distorts the apparent elevation of the map’s topography in order to emphasize vertical features, which might otherwise appear too small to identify relative to the corresponding horizontal scale.
valley : 1. A low area between hills or mountains, often with a river running through it.2. A depression that is longer than it is wide.
vale : Another name for a valley.
urbanization : The process by which a human population shifts from rural to urban residency, the gradual increase in the proportion of people living in urban areas such as towns and cities, and the ways in which human societies respond and adapt to this change. Urbanization may be characterized as a specific condition at a set time (e.g. the proportion of the total population or physical area within a given set of towns or cities) or as an increase in that condition over time. It precipitates enormous social, economic, and environmental changes for the planet as a whole.
urban studies : The study of the development of cities and urban areas, especially from historical, architectural, or civic planning perspectives.
urban sprawl : The unrestricted growth of housing, commercial development, and roads (typically of low densities) over large expanses of land, usually within or near an existing urban or suburban area and with little concern for civic planning. It is often considered a type of urbanization and almost always carries negative connotations.
