The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin.
A nineteenth and early twentieth century approach to the study of geography that argued that the general laws sought by human geographers could be found in the physical sciences. Geography was therefore the study of how the physical enviroment caused human activities.
(uniform or homogeneous region) An area in which everyone shares in one or more distinctive characteristics.
International Date Line
An arc that for the most part follows 180° longitude, although it deviates in several places to avoid dividing land areas. When you cross this heading east (toward America), the clock moves back 24 hours, or one entire day. When you go west (toward Asia), the calendar moves ahead one day.
The numbering system used to indicate the location of parallels drawn on a globe and measuring distance north and south of the equator (0°).
The numbering system used to indicate the location of meridians drawn on a globe and measuring distance east and west of the prime meridian (0°).
A projection where it's advantages are as follows: Shape is distorted very little, direction is consistent, and the map is rectangular. Disadvantages: area is grossly distorted toward the poles, making high-latitude places look much larger than they actually are.
A circle drawn around the globe parallel to the equator and at right angles to the meridians.
The theory that the physical enviroment may set limits on human actions, but people have the ability to adjust to the physical enviroment and choose a course of action from many alternatives.
The meridian, designated as 0° langitude, which passes through the Royal Observatory at Greenwhich, England.
The acquisition of data about Earth's surface from a satellite orbiting the planet or other long-distance methods.
A projection which is useful for displaying information across the ocean. The major disadvantage is that by allcating space to the oceans, the land areas are much smaller than on interrupted maps of the same size.
Generally, the relationship between the portion of Earth being studied and Earth as a whole, specifically the relationship between the size of an object on a map and the size of the actual feature on Earth's surface.
The reduction in the time it takes to diffuse something to a distant place, as a result of improved communications and transportation systems.
The spread of an underlying principle, even though a specific characteristic is rejected.
