Globe- A spherical representation of the earth or of the constellations with a map on the surface.
Map-
A diagrammatic representation of an area of land or sea showing physical features, cities, roads | Latitude- The angular distance of a place north or south of the earth's equator, usually expressed in degrees and minutes.Longitude- The angular distance of a place east or west of the meridian at Greenwich, England, or west of the standard meridian of a celestial...: "at a longitude of 2° W"; "lines of longitudeEquator- An imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheresNorth Pole- also known as the Geographic North Pole or Terrestrial North Pole, is, subject to the caveats explained below, defined as the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It should not be confused with the North Magnetic Pole.South Pole-also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface. It is the southernmost point on the surface of the Earth and lies on the opposite side of the Earth from the North PoleInternational Dateline-An imaginary line through the Pacific Ocean roughly corresponding to 180° longitude, to the east of which, by international agreement, the calendar date is one day earlier than to the west. 1. Prime Meridian-A planet's meridian adopted as the zero of longitude. 2. The earth's zero of longitude, which by convention passes through Greenwich, England.Grid-A framework of spaced bars that are parallel to or cross each other; a grating.Tropic of Cancer-The parallel of latitude 23°27 north of the equator, the northern boundary of the Torrid Zone, and the most northerly latitude at which the sun can shine directly overhead.Tropic of Capricorn-The parallel of latitude 23°27 south of the equator, the southern boundary of the Torrid Zone, and the most southerly latitude at which the sun can shine directly overhead. 1. Direction- A course along which someone or something moves. 2. The course that must be taken in order to reach a destinationElevation-vertical distance from a datum plane, usually mean sea level to a point above the earth. Often used synonymously with altitude, elevation is the height on the earth's surface and altitude, the height in space above the surface. The elevation of a feature is calculated through such surveying techniques as trigonometric triangulation and aerial photogrammetry. Elevation is represented by using contours of equal elevation lines, three-dimensional computer graphics representation, or molded three-dimensional plastic models.Sea Level-The level of the ocean's surface, especially the level halfway between mean high and low tide, used as a standard in reckoning land elevation or sea depths.Canyon-a gorge or ravine, esp in North America, usually formed by the down-cutting of a river in a dry area where there is insufficient rainfall to erode the sides of the valleyCoast- the line or zone where the land meets the sea or some other large expanse of waterContinent-The major land masses of the earth. According to tradition most people speak of seven continents on the planet. However, geologically there are six large distinct land masses on the earth so many geographers and scientists refer to six.Delta-The often triangular-shaped alluvial deposition area at the mouth of a river. Named for the shape of the Greek letter delta, shaped as a trangle. The archetypal delta is the Nile Delta in northern Egypt.Gulf- A large area of a sea or ocean partially enclosed by land, especially a long landlocked portion of sea opening through a strait.Harbor-A sheltered part of a body of water deep enough to provide anchorage for shipsIsland- any area of land smaller than a continent and entirely surrounded bywater. Islands may occur in oceans, seas, lakes, or rivers.Archipelago- a group of islandLakeA large inland body of fresh water or salt water.Mountain- s a large landform that stretches above the surrounding land in a limited area usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanismMountain ranges- A series of mountain ridges alike in form, direction, and origin.Ocean-The entire body of salt water that covers more than 70 percent of the earth's surface.Peninsula-a narrow strip of land projecting into a sea or lake from the mainlandPlain/pumper-Any relatively level area of the Earth's surface that exhibits gentle slopes and small local reliefPlateau- a wide mainly level area of elevated landRiver-a natural and continuous flow of water in a long line across a country into the seaSea- The continuous body of salt water covering most of the earth's surface, especially this body regarded as a geophysical entity distinct from earth and sky.Valley- a long depression in the land surface, usually containing a river, formed by erosion or by movements in the earth's crustForest-Strait- A narrow channel joining two larger bodies of waterRain forest-A dense evergreen forest with an annual rainfall of at least 406 centimeters (160 inches). Rainforests are often, but not always, located in tropical regions.Permafrost-ground that is permanently frozen, often to great depths, the surface sometimes thawing in the summerTundra-A treeless area between the icecap and the tree line of Arctic regions, having a permanently frozen subsoil and supporting low-growing vegetation such as lichens, mosses, and stunted shrubs.Desert-A dry, often sandy region of little rainfall, extreme temperatures, and sparse vegetation.b. A region of permanent cold that is largely or entirely devoid of life.c. An apparently lifeless area of water.Prairies-An extensive area of flat or rolling, predominantly treeless grassland, especially the large tract or plain of central North America. |
