|---|---|
| Geography | The study of thee earths surface and the processes that shape it, the connections between places, and the complex relationship between people and their environment |

| Absolute location | the position on thee earth in which a place can be found |
| Hemisphere | a half of the earth;the equator divides the northern and southern hemispheres; the prime meridian divides the eastern and western hemispheres |
| Relative Location | the position of a place in a relation to another place |
| Character of a place | the physical and human characteristics that help to distinguish place from other places |
| perception | a viewpoint that id influenced by ones own culture and experiences |
| Formal region | a group of places that have similar attributes and for example a political region |
| functional region | a group of places connected by movement, for example,the region drained by the amazon river and its tributaries |
| perceptual region | a group of places that is defined by peoples feelings and attitudes feelings and attitudes |
| core | the earths center, consisting of very hot metal that is dense and solid in the inner core, and molten and/or liquid in the outter core |
| Mantle | a thick layer of mostly solid rock beneath the earths crust that surrounds the earths core |
| Crust | the rocky surface layer of the earth |

| acid rain | rain whose high concentration of chemicals usually from industrial pollution, pollutes water kills plant and animal life eats away at the surface stone and rock a form of chemical weathering |
| erosion | the movement of weathered materials, including gravel and soil and sand, usually caused by water wind and glaciers |
