AP Human Geography

Unit 1

QuestionAnswer
Density A) Arithmetic The population of a country or region expressed as an average per unit area. This figure is derived by dividing the population of the areal unit by the number of square kilometers or miles that make up the unit. This measure assumes that there is an even distribution of the population over land. No country however has an evenly distributed population. For example, arithmetic population measures do not reflect the emptiness of Alaska and the sparseness of population in much of the West. Also, Egypt's population of 73.3 million has a moderate arithmetic density of 190 per square mile. Yet Egypt's territory of 386,660 miles is mostly desert and the majority of the population is crowded into the valley and delta of the Nile River. 98% of all Egyptians live on just 3% of the country's land, so the arithmetic population density is useless.
Demography Study of population.
Density B) Physiological The number of people per unit of arable land. Relates the total population of a country or region to the area of farmable land it contains. Better measurement of population density. Take the case of Egypt again. Millions live in its great cities like Cairo and Alexandria and smaller urban centers and also irrigated farmlands. The physiological pop. density for Egypt is 6319 per square mile. This number is far more reflexive of Egypt's population pressure, and it continues to rise rapidly despite Egypt's efforts to expand its irrigated farmlands.
Diffusion A) Hearth An area where cultural traits develop and from which the cultural traits diffuse. Place where idea or culture originates. Example)---> the religion of Islam was traced to around the cities of Mecca and Medina on the Arabian Peninsula in the 500s C.E. the term for a trait with many hearths that developed independent of each other is independent invention. (example) Agriculture can be traced to several hearths thousands of years apart.
Diffusion B) Relocation Movement of people who have adopted the innovation to a distant group. It involves the actual movement of individuals who have already adopted the idea or innovation, where they proceed to disseminate it. Occurs most frequently by migration. When migrants move from their homeland, they take their cultural traits with them. They can develop ethnic neighborhoods in other places where they maintain their culture. If the homeland of the immigrants loses enough of its population, the cultural customs may fade in the hearth while gaining strength in the ethnic neighborhoods abroad.
Diffusion C) Expansion When an innovation or idea develops in a hearth and remains strong there while spreading outwards. Example is spread of Islam from Arabian Peninsula to Egypt and North Africa, through SW Asia, and into West Africa.
Diffusion D) Hierarchical Form of diffusion in which an idea or innovation spreads by passing first among the most connected places or peoples. Usually is expansion to some susceptible groups but leapfrogs others. Example= Birkenstock sandals in Germany. people in and that went to Germany first adopted it. Were sold in health food stores, mostly in areas with a large population of people involved in outdoor activities. Examples are also AIDS, Terrorism, and foreign language movies.
Diffusion E) Contagious A form of diffusion in which nearly all adjacent individuals are affected. Examples are measles and smallpox. Examples are diseases. Could also be ideas or music but not always.
Diffusion F) Stimulus Diffusion in which a cultural adaptation is created as result of the introduction of a cultural trait from another place. Not all ideas introduced to a population is readily adopted. Yet these ideas can still have an impact somewhat on the population. EXAMPLE is the introduction of the hamburger in India. But the Hindu prohibition against consumption of beef presented a cultural obstacle for this food item. Instead, retailers began selling burgers made of vegetable products. This adaptation was stimulated by the introduction of the hamburger that took on a new form in the cultural context in which it was used.
Absolute Distance The distance that can be measured with a standard unit of length, such as a mile or kilometer Relative Distance A measure of distance that includes the costs of overcoming the friction of absolute distance separating two places. Often relative distance describes the amount of social, cultural, or economic connectivity between two places.
Environmental Determinism Holds that human behavior, individually and collectively, is affected by- even controlled or determined by- the physical environment. Suggests that climate is the critical factor in how humans behave.
GIS (Geographic Information System) A collection of computer hardware and software that permits spatial data to be collected, recorded, stored, retrieved, manipulated, analyzed, and displayed to the user. Geographers use GIS to compare a variety of spatial data by combining layers of spatial data in a computerized environment, creating maps in which patterns and processes are superimposed. Geographers use it for human and physical geographic research.
Global Positioning System (GPS) Satellite based system used to determine the absolute location of places or geographic features.
International Dateline- 180° longitude, although it deviates in several places to avoid dividing land areas. When you cross the International Date Line 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. prime meridian----->the meridian that passes through the Royal Observatory at Greenwich, England, is 0 degrees longitude
Absolute Location The position or place of a certain item on the surface of the Earth. Expressed in degrees, minutes, and seconds of latitude, 0 degrees to ninety degrees north or south of the equator, and longitude, 0 degrees to 180 degrees east or west of the Prime Meridian passing through Greenwich, England (a suburb of London). Absolute Location helps us calculate distances between places.
Relative Location The regional position or situation of a place relative to the position of other places. Distance, accessibility, and connectivity affect relative location. Examples are such as 'Chicago is on Lake Michigan, south of Milwaukee". Another is "Chicago is the hub of the corn and soybean markets in the Midwest". These are descriptors of Chicago relative to other places. Absolute Locations do not change, but relative locations are constantly modified and changed over time. For example, Fredericksburg, Virginia is located halfway between D.C. and Richmond, Virginia. Today it is a suburb of D.C.
Site The internal physical attributes of a place, including its absolute location, its spatial character and physical setting. Situation Situation The external locational attributes of a place; relative location or regional position with reference to other non-local places.
Map Scale The scale of a map is defined as the ratio of a distance on the map to the corresponding distance on the ground.
Thematic Map (Reference Maps- shows locations of places and geographic features). Maps that tell stories, typically showing the degree of some attribute or the movement of a geographic phenomenon. Example is a map of "Where Pennsylvania Students Prefer to Live"
Statistical Map A special type of map in which the variation in quantity of a factor such as rainfall, population, or crops in a geographic area is indicated; a dot map is one type. Cartogram A cartogram is a map in which some thematic mapping variable – such as travel time or Gross National Product – is substituted for land area or distance. The geometry or space of the map is distorted in order to convey the information of this alternate variable
Dot Maps Maps where one dot represents a certain number of a phenomenon, such as population. usually used for populations Choropleth Map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income.
Isoline Map (Contour map) a line on a map connecting places registering the same amount or ratio of some geographical or meteorological phenomenon or phenomena Also called isogram, isoline
Mental Map (Cognitive Map) Image or picture of the way space is organized as determined by an individual's perception, impression, and knowledge of that space. Example is even though someone never went to the Great Plains, he or she might have a good idea of what the great plains may look like from studying maps and reading atlases and hearing about it. This may also apply to finding your way through places using your mental map of the places you go to a lot or remember well from.
Natural Landscape the overall appearance of an area. Most landscapes are comprised of combination of natural and human-induced influences.
Possibilism Geographic viewpoint- a response to determinism- that holds that human decision making, not the environment, is the crucial factor in cultural development. Nonetheless, possibilists view the environment as providing a set of broad constraints that limits the possibilities of human choice.
Map Projection SEE BINDER FOR THE PROJECTIONS A mathematical method that involves transferring the earth's sphere onto a flat surface. The term can also be used to describe the type of map that results from the process of projecting. All map projections have distortions in either area, direction, d
Formal/Uniform Region A type of region marked by a certain degree of homogeneity in one or more phenomena; also called uniform region or homogeneous region. Area marked by visible uniformity. Example is a desert basin marked by severe aridity, sand surface, and steep surrounding mountain slopes. Formal regions can also be defined by cultural traits. Another example is the region of Europe where French is spoken by 90 percent or more of the population.
Functional Region (Product of interactions, of movement of various kinds). A region defined by a particular set of activities or interactions that occur within it. Example is a city that has surrounding region with workers commuting either to the downtown area or to subsidiary centers such as office parks and shopping malls. The entire urban area is defined by people moving toward and within it. people within the region function together politically, socially, and economically. It is a spatial system with boundaries that are defined by the limits of that system.
Perceptual Region Are intellectual constructs designed to help us understand the nature and distribution of phenomena in human geography. region that only exists as a conceptualization or idea and not as a physically demarcated entity These perceptions are based on our accumulated knowledge about such regions and cultures. Examples are on how people view what is the 'West" or "Mid-Atlantic regions".
Remote Sensing A method of collecting data or information through the use of instruments (e.g. satellites) that are physically distant from the area of object of study. Shows us the major areas of impact of natural disasters, environmental change over short and long periods,
Scale Representation of real world phenomena at a certain level of reduction or generalization. In cartography it is the ratio of map distance to ground distance; indicated on a map as a bar graph; representative fraction, and/or verbal statement.
Sequent Occupance The notion that successive societies leave their cultural imprints on a place, each contributing to the cumulative cultural landscape. When occupiers arrive at a landscape, they can bring their own technological and cultural traditions- and transform the landscape accordingly. They can also be influenced by what they find when they arrive- and leave some of it in place.
Spatial Pertaining to space on the Earth's surface; sometimes used as a synonym for geographic.
Distance Decay (Suggests that the impact of a function or activity will decline as one moves away from its point of origin). The effects of distance on interaction, generally the greater the distance the less interaction. Usually leads to many migrants moving less far than they originally contemplated.
Friction Distance The increase in time and cost that usually comes with increasing distance. Example is a raw material being shipped hundreds of miles rather than closer from where it was shipped.
Time-Space Compression A term associated with the work of David Harvey that refers to the social and psychological effects of living in a world in which "time-space convergence" has rapidly reached a high level of intensity. Explains how quickly innovations diffuse and refers to how interlinked 2 places are through transportation and communication technologies. time-space convergence (Refers to the greatly accelerated movement of goods, information, and ideas during the 20th century made possible by technological innovations in transportation and communications.
Time Zones Any of the 24 divisions of the Earth's surface used to determine the local time for any given locality. Each zone is roughly 15° of longitude in width, with local variations for economic and political convenience. The International Meridian Local time is one hour ahead for each time zone as one travels east and one hour behind for each time zone as one travels west. Conference in 1884 established the prime meridian as the starting point for the 24 zones.
Built Landscape The built landscape is represented by those features and patterns reflecting human occupation and use of natural resources (examples) a city, a town, a road, a factory. things like that.
Cultural Landscape The visible imprint of human activity and culture on the landscape. Basically, it's landscape altered or imprinted by humans. The layers of buildings, forms, artifacts sequentially imprinted on the landscape by the activities of various human occupants. Any cultural landscape has layers of imprints from years of human activity. As successive occupiers arrive, they bring their own technological and cultural traditions- and transform the landscape. They could also be influenced by what they find when they come- and leave some of it in place.
