1)Geography | The study of earths surface and the process that shape it, the connections between people and their environments. |
2)GIS | A geographic information system, which uses computer technology to collect and analyze data about the earths surface in order to solve geographic problems. |
3)Absolute location | The position on the earth in which a place can be found. |
4)Hemisphere | a half of the earth; the Equator divides the Northern and Southern hemisphere's; the prime Meridian divides the Eastern and western hemisphere's. |
5)Relative location | The position of a place in relation to another place. |
6)Character of a place | The physical and human characteristic that help to distinguish a place from other places. |
7)Perception | A viewpoint that is influenced by ones own culture and experiences. |
8)Formal Region | A group of places that have similar attributes, for example, a political region. |
9)Function region | A group of places connected by movement, for example, the region drained by the Amazon river and its tributaries |
10)Perceptual region | A group of places that is defined by peoples feelings and attitude. |
11)Core | The earths center, consisting of very hot metal that is dense and solid in the inner core and molten, or liquid, in the outer core. |
12)Mantle | A thick layer of mostly solid rock beneath the earths crust that surrounds the earths core. |
13)Crust | The solid, rocky, surface layer of the earth. |
14)Lithosphere | The surface features of the earth, including soil, rocks and landforms. |
15)Atmosphere | The layer of gases, water vapor, and other substances above the earth. |
16)Hydrosphere | The water contained in oceans, lakes, rivers, and under the ground. |
17)Biosphere | The world of plants, animals, and other living things in earths land and water. |
18)Continent | Any of the seven large landmass of the earths surface:Africa, Antarctica, Asia, Australia, Europe, North america, and south america. |
20)Relief | The distance in elevation, or height, of the landforms in any particular area. |
21)Plate Tectonics | The theory that the earths outer shell is composed of a number of large, unanchored plates, or slabs of rocks, whose constant movement explains earthquakes and volcanic activity. |
22)Continental drift theory | The idea that continents slowly shift their positions due to movement of the tectonic plates on which they ride. |
23)Ring of fire | A ring of volcanic mountains surrounding the Pacific Ocean. |
24)Weathering | The chemical or mechanical process by which rock is gradually broken down, eventually becoming spoil. |
25)Mechanical weathering | The actual breaking up or physical weakening of rock by process such as ice and roots, |
26)Chemical weathering | The process by which the actual chemical structure of rock is changed, usually when water and carbon dioxide cause a breakdown of the rock. |
28)Acid rain | Rain whose high concentration of chemicals, usually from industrail pollution, pollutes water, skills plant and animal life, and eats away at the surface of stone and rock, a form of chemical weathering. |
29)Erroison | The movement of weathered materials, including gravel, soil, and sand, usually caused by water, wind, and glaciers. |
30)Sediment | Particles of soil and rock carried and deposited by water, wind, ice. |
31)loess | Fine-grained, mineral-rich loam, dust, or slit deposited by the wind. |
