Ch 1

TermDefinition
1. Geography The study of the earths surface and the processes that shape the connection between places, and the complex relationships between people and the 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 earth in which a place can be found.
4. Heispheres 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 viewpoint that is influenced by ones own culture and experiences.
8. Formal Regions a group of places that have similar attributes, for ex, a political region.
9. Functional Regions group of places connected by movement, for example, the region drained by the amazon river and its tributaries.
10. Perceptual Regions a group off places that is defined by people's feelings and attributes.
11.Core The earth's 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 Thick layer of mostly solid rock beneath the earth's crust that surrounds the earth's core.
13. Crust Solid, Rocky surface that is covering the earth.
14. Lithospere The surface features of the earth, soil, rock, and land forms.
15. Atmospere Layer of gases, water vapor, and other substances above the earth.
16. Hydrosphere The water contained in oceans, lakes, and river, and under the ground.

22. Ring of Fire A ring of volcanic mountains surrounding the Pacific Ocean.
23. Weathering Chemical or mechanical process by which rock is gradually broken down, eventually becoming soil.
24. Mechanical Weathering The actual breaking up of physical or physical weakening of rock by forces such as ices and roots.
25. Chemical Weathering Process in which the actual chemical structure of the 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, sand, usually caused by wind, water 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.
