1.Geography | The study of earth's surface and the processes that shape it,the connections between places,and the complex relationships between people and their environments. |
2.GIS | a geographic information system,which uses computer technology to collect and analyze data about the earth's 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 hemispheres; the Prime Meridian divides the eastern and western hemispheres. |
5.Relative Location | The position of a place in relation to another place. |
6.Character Of A Place | The physical and human characteristics that help to distinguish a place from other places. |
7.Perception | A view point that is influenced by one's own culture and experiences. |
8.Formal Region | A group of places that have similar attributes. |
9.Functional Region | A group of places connected by movement. |
10.Perceptual Region | A group of places that is defined by peoples feelings and attributes. |
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 earth's 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 the oceans,lakes,rivers,and under the ground. |
17.Biosphere | The world of plants,animals,and other living things in earth's land and waters. |
18.Continent | Any of the seven large landmasses of the earth's surface:Africa,Antarctica,Asia,Australia,Europe,North America,and South America. |
19.Relief | The differences in elevation,or height, of the landforms in any particular area. |
20.Plate Tectonics | The theory that the earth's outer shell is composed of a number of large, unanchored plates,or slabs of rock,whose constant movement explains earthquakes and volcanic activity. |
21.Continental Drift Theory | The idea that continents slowly shift their positions due to the movement of the tectonic plates on which they side. |
22.Ring Of Fire | A ring of volcanic mountains surrounding the Pacific Ocean. |
23.Weathering | The chemical or mechanical process by which rock is gradually broken down, eventually becoming soil. |
24.Mechanical Weathering | The actual breaking up of physical weakening of rock by forces such as ice and roots. |
25.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. |
26.Acid Rain | Rain whose high concentration of chemicals, usually from industrial pollution, pollutes water, kills plant and animal life, and eats away at the surface of stone and rock: a form of chemical weathering |
27.Erosion | The movement of weathered materials, including gravel, soil, and sand, usually caused by water, wind, and glaciers. |
28.Sediment | Small particles of soil, sand, and gravel carried and deposited by water. |
29.Loess | Fine grained, mineral-rich loam, dust, or silt deposited by the wind. |
