Geography | The topographical features of a region, usually of the Earth, sometimes of the planets. |
Character of a Place | Moral or ethical quality. |
Absolute Locations | The exact Latitude and Longitude of a spot on Earth. |
GIS | A system designed to capture, sore, manipulate, analyze, manage, and present all types of spatial or geographical data. |
Hemisphere | Half of the terrestrial globe or celestial sphere. |
Relative Location | A point of place in relation to another point or place. |
Perception | Immediate or intuitive recognition or appreciation, as of moral, psychological or aesthetic qualities, |
Relief | The difference in elevation between parts of the Earth's surface. |
Formal Region | A central place and the surrounding areas that are dependent upon that place, such as a metropolitan area. |
Functional Region | A central place and surrounding areas by it. |
Perceptual Region | Reflect human feelings and attitudes about areas. |
Mantle | The portion of the earth,, about 1800 miles thick, between the crust and the core. |
Weathering | The various mechanical and chemical processes that cause exposed rock to decompose. |
Mechanical Weathering | Any of the various weathering processes that cause physical disintegration of exposed rock without change in the chemical compound of the rock. |
Acid Rain | Precipitation, as rain, snow, or sleet, containing high concentrations of acid-forming chemicals, as the pollutants from coal smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combined with water vapor. |
Core | A cylindrical sample of earth, mineral, or rock extracted from the ground by means of a corer so that the strata are undisturbed in the sample. |
Climates | The composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of year. |
Chemical Weathering | Any of the various weathering processes that cause exposed rock to undergo chemical decomposition, changing the chemical and mineralogical composition of the rock. |
Lithosphere | The solid portion of earth. |
Erosion | The process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc. |
Ecosystems | A system, or a group of interconnected elements, formed by the interaction or a community of organisms with their environment. |
Atmosphere | The gaseous envelope surrounding the earth. |
Hydrosphere | The water on or surrounding the surface of the globe, including the water of the oceans, and the water in the atmosphere |
Sediment | MIneral or organic matter deposited by water, air, or ice. |
Biosphere | The part of the earth's crust, waters, and atmosphere that supports life. |
Continent | One of the main landmasses of the globe, usually reckoned as seven in number (Europe, Asia, Africa, North America, South America, Australia, and Antarctica). |
Glacier | An extended mass of ice formed from snow falling and accumulating over the year and moving very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. |
Loess | A loamy deposit formed by wind, usually yellowish and calcareous, common in the Mississippi Valley and in Europe and Asia. |
Plate Tectonics | A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle. |
Continental Drift | The lateral movement of continents resulting from the motion of crustal plates. |
Theory of Ring of Fire | A string of volcanoes that encircles the Pacific Ocean. |
Moraine | A ridge, mound, or irregular mass of unstratified glacial drift, chiefly boulder, gravel, sand, and clay. |
