THE WORLD IN SPATIAL TERMS

STANDARD 1: How to Use Maps and Other Geographic Representations, Tools, and Technologies to Acquire, Process, and Report Information From a Spatial Perspective

Geographic information is compiled, organized, manipulated, stored, and made accessible in a great many ways. It is essential that students develop an understanding of these ways so they can make use of the information and learn the skills associated with developing and communicating information from a spatial perspective.

The study and practice of geography require the use of geographic representations, tools, and technologies. Geographic representations consist primarily of maps and also include globes, graphs, diagrams, aerial and other photographs, and satellite-produced images. Tools and technologies consist primarily of reference works such as almanacs, gazetteers, geographic dictionaries, statistical abstracts, and other data compilations.

Maps are graphic representations of selected aspects of Earth’s surface. They represent compilations of geographic information about selected physical and human features. Using point, line, and area symbols, as well as color, they show how those features are located, arranged, distributed, and related to one another. They range in appearance and purpose from a simple freehand line drawing of how to get to a friend’s house to a complex multicolor depiction of atmospheric conditions used in weather forecasting. No single map can show everything, and the features depicted on each map are selected to fit a particular purpose. Maps can depict not only visible surface features such as rivers, seacoasts, roads, and towns, but also underground features such as subway systems, tunnels, and geographic formations. They can depict abstract features such as political boundaries, population densities, and lines of latitude and longitude.

In the classroom, maps serve both as repositories of many kinds of geographical information and as an essential means of imparting that information to students. Maps constitute a critical element of geography education. However, they do have limitations. One major limitation is that it is not possible to accurately represent the round Earth on a flat surface without distorting at least one Earth property, such as distance, direction, or size and shape of land and water bodies. Therefore, different map projections are used to depict different Earth properties (e.g., equal area projections show landmasses in correct areal proportion to one another but with distortions of shape). No single map can accurately depict all Earth’s properties, so it is essential that students know how to look at a given map and know which properties are rendered correctly and which are distorted.

As scale models, globes constitute the most accurate representation of Earth in terms of the properties of Earth’s surface features—area, relative size and shape, scale and distance, and compass direction are proportionately and therefore correctly represented on globes. Globes present an essential overview of Earth, and they can be very useful in the teaching of such concepts as location, spatial patterns, Earth-Sun relationships, and time. However, globes have limitations: They are cumbersome to handle and store, small-scale, and only half of Earth can be observed at once.

In addition to maps and globes, graphs, diagrams, aerial and other photographs, and satellite-produced images also provide valuable information about spatial patterns on Earth. They are very diversified in the kinds of information they present and, under certain circumstances, they have classroom value as both supplements to and substitutes for globes and maps. However, they also have limitations: For instance, they may not be immediately understandable to students, who may need special instruction in their use.

The tools and technologies used in geography encompass a great variety of reference works, ranging from encyclopedias and other multivolume publications covering many topics to single reports on specialized subjects. Some of these works are in narrative form; some are primarily compilations of data represented in tabular form. Some are easy to understand and use; some are not. Students need to develop an understanding of the kinds of reference works that are available to them, as well as learn how to obtain information from the works, how to gauge the general reliability of that information, and how to convert information from one form to another (e.g., take data from a table and present it in a written narrative).

Traditionally reference works have been available solely in printed form. Currently, however, more and more of them are also being made available in the form of computer-based databases and computer-based information systems. This development is a result of computer systems becoming an essential tool for storing, analyzing, and presenting spatial information. Because of their speed and flexibility, such systems enable the geographically informed person to explore, manipulate, and assess spatial data far more effectively than do conventional printed materials. Furthermore, current developments in multimedia techniques such as animation, sound, and interactive learning procedures, promise an even more flexible and creative approach to geographic learning.

Throughout their K-12 schooling, students should continue to have direct experience with a wide variety of geographic representations, especially maps. Maps can become increasingly abstract with each succeeding grade level reflecting the developmental changes in students’ abilities to represent and manipulate spatial and symbolic information. In the early grades, students should come to see maps, like the written word, as a source of information about their world. They should be given opportunities to read and interpret different kinds of maps and to create maps of their classroom, school, and neighborhood using various media (e.g., pencils, cutouts). Subsequent experiences in map reading and mapmaking should become more sophisticated and abstract as students develop a more comprehensive understanding of the knowledge, skills, and perspectives involved in maps and mapping activities.

In addition, students should be given an opportunity to become familiar with computer systems and computer-based geographic information systems. As such systems become increasingly common in the home, school, and workplace for many different purposes, people will learn to use them as comfortably and effectively as they have traditionally used printed materials. Therefore, it is essential that students of geography be exposed to as many forms of geographic data processing as possible and come to understand the role of computer systems in both the study and practice of geography.

Knowing how to identify, access, evaluate, and use all of these geographic resources will ensure students of a rich school experience in geography and the prospect of having an effective array of problem-solving and decision-making skills for use in both their other educational pursuits and their adult years.

STANDARD 2: How to Use Mental Maps to Organize Information About People, Places, and Environments in a Spatial Context

To be geographically informed, a person must keep in mind a lot of information about people, places, and environments and must be able to organize this information in the appropriate spatial context. A very effective way of doing this is to create and use what can be called “mental maps.” Such a map is an individual’s internalized representation of some aspect or aspects of Earth’s surface. It represents what the person knows about the locations and the characteristics of places at a variety of scales (local to global) from the layout of the student’s bedroom to the distribution of oceans and continents on the surface of the Earth. These maps in the mind provide students with an essential means of making sense of the world, and of storing and recalling information about the shapes and patterns of the physical and human features of Earth. Learning how to create and use mental maps, therefore, is a fundamental part of the process of becoming geographically informed.

Mental maps have several distinguishing characteristics:

• Mental maps are personal and idiosyncratic and are usually a mixture of both objective knowledge and subjective perceptions. They contain objective and precise knowledge about the location of geographic features, such as continents, countries, cities, mountain ranges, and oceans. They also contain more subjective and less precise information, such as impressions of places, rough estimates of relative size, shape, and location, and a general sense of certain connections between places as well as priorities that reflect the mapmaker’s own predilections.
• Mental maps are used in some form by all people throughout their lives. Such maps enable people to know what routes to take when traveling, comprehend what others say or write about various places, and develop an understanding of the world. Mental maps represent ever changing summaries of spatial knowledge and serve as indicators of how well people know the spatial characteristics of places. People develop and refine their mental maps through personal experience and through learning from teachers in the media. They refine at least some of their maps to ever higher levels of completeness and accuracy, and they continue to add information so the maps reflect a growing understanding of a changing world. Critical geographic observation is essential to this development and refinement process, because mental maps reflect people’s skill in observing and thinking about the world in spatial terms (and have nothing to do with their ability to draw).
• As students read, hear, observe, and think more about the world around them, they can add more detail and structure to their maps. As students get older, their mental maps accumulate multiple layers of useful information, and this growth in complexity and utility can provide them with a sense of satisfaction as more places and events in the world can be placed into meaningful spatial context.

If geography is to be useful in creating a framework for understanding the world—past, present, and future—then coherent mental maps must take shape and become increasingly refined as students progress through their school years. Students should be encouraged to develop and update their mental maps to ensure that they continue to have essential knowledge of place location, place characteristics, and other information that will assist them in personal decision-making and in establishing a broad-based perception of Earth from a local to a global perspective. In addition, they need to understand that developing mental maps is a basic skill for everyone who wants to engage in a lifetime of geographic understanding.

PLACES AND REGIONS

STANDARD 5: That People Create Regions to Interpret Earth’s Complexity

Region is a concept that is used to identify and organize areas of Earth’s surface for various purposes. A region has certain characteristics that give it a measure of cohesiveness and distinctiveness that set it apart from other regions. As worlds within worlds, regions can be used to simplify the whole by organizing Earth’s surface on the basis of the presence or absence of selected physical and human characteristics. As a result, regions are human constructs whose boundaries and characteristics are derived from sets of specific criteria. They can vary in scale from local to global; overlap or be mutually exclusive; exhaustively partition the entire world or capture only selected portions of it. They can nest within one another, forming a multilevel mosaic. Understanding the idea of region and the process of regionalization is fundamental to being geographically informed.

Understanding the nature of regions requires a flexible approach to the world. The criteria used to define and delimit regions can be spatially precise as coastlines and political boundaries or as spatially amorphous as suggesting the general location of people with allegiances to a particular professional athletic team or identifying a market area for distributing the recordings of a specific genre of music. Regions can be as small as a neighborhood or as vast as a territorial expanse covering thousands of square miles in which the inhabitants speak the same language. They can be areas joining people in common causes where they can become areas for conflict, both internal and external. Geographers define regions in three basic ways:

The first type is the formal region. It is characterized by a common human property, such as the presence of people who share a particular language, religion, nationality, political identity or culture, or by a common physical property, such as the presence of a particular type of climate, landform, or vegetation. Political entities such as counties, states, countries, and provinces are formal regions because they are defined by a common political identity. Other formal regions include climate regions (e.g., areas with a Mediterranean climate), landform regions (e.g., the Ridge and Valley and Piedmont regions of Pennsylvania), and economic regions (e.g., the wheat belt of Kansas, the citrus-growing areas of south Texas, and the irrigated farmlands of the Central Valley of California). Formal regions can be defined by measures of population, per capita income, ethnic background, crop production, population density and distribution, or industrial production, or by mapping physical characteristics such as temperature, rainfall, growing season, and average date of first and last frost.

The second type of region is the functional region. It is organized around a node or focal point with the surrounding areas linked to that node by transportation systems, communication systems, or other economic association involving such activities as manufacturing and retail trading. A typical functional region is a metropolitan area (MA) as defined by the Bureau of Census. For example, the New York MA is a functional region that covers parts of several states. It is linked by commuting patterns, trade flows, television and radio broadcasts, newspapers, travel for recreation and entertainment. Other functional regions include shopping regions centered on malls or supermarkets, area served by branch banks, and ports and their hinterlands.

The third type of region is the perceptual region. It is a construct that reflects human feelings and attitudes about areas and is therefore defined by people’s shared subjective images of those areas. It tends to reflect the element of people’s mental maps, and, although it may help to impose a personal sense of order and structure on the world, it often does so on the basis of stereotypes that may be inappropriate or incorrect. Thus southern California, Dixie, and the upper Midwest are perceptual regions that are thought of as being spatial units, although they do not have precise borders or even commonly accepted regional characteristics and names.

Some regions, especially formal regions, tend to be stable in spatial definition, but may undergo change in character. Others, especially functional regions, may retain certain basic characteristics, but may undergo spatial redefinition over time. Yet other regions, particularly perceptual regions, are likely to vary over time in both spatial extent and character.

Regional change, in the context of the human spatial organization of Earth’s surface, is an area of study that provides students with opportunities to examine and learn about the complex web of demographic and economic changes that occur.

Regions serve as a valuable organizing technique for framing detailed knowledge of the world and for asking geographic questions. Because regions are examples of geographic generalizations, students can learn about the characteristics of other regions of the world by knowing about one region. Knowing about the physical processes that create the Mediterranean climate and vegetation of southern California, for example, can serve as an analogue for learning about other regions with Mediterranean climates and vegetation in Australia, Europe, South America, and Africa. Regions provide a context for discussing similarities and differences between parts of the world.

Through understanding the idea of region, students can apply geographic knowledge, skills, and perspectives to solving problems as immediate as making an informed decision about a neighborhood zoning issue or as long-range as predicting the reconfiguration of political and economic alliances owing to resource shortages or changes in the global ecosystem. Most importantly, studying regions enables students to synthesize their understanding of the physical and human properties of Earth’s surface at scales that range from local to global.

STANDARD 16: The Changes That Occur in the Meaning, Use, Distribution, and Importance of Resources

A resource is any physical material that constitutes part of Earth and which people need and value. There are three basic resources—land, water, and air—that are essential to human survival. However, any other natural material also becomes a resource if and when it becomes valuable to humans. The geographically informed person must develop an understanding of this concept and of the changes in the spatial distribution, quantity, and quality of resources on Earth’s surface.

Those changes occur because a resource is a cultural concept, with the value attached to any given resource varying from culture to culture and period to period. Value can be expressed in economic or monetary terms, in legal terms (as in the Clean Air Act), in terms of risk assessment, or in terms of ethics (the responsibility to preserve our National Parks for future generations). The value of a resource depends on human needs and the technology available for its extraction and use. Rock oil seeping from rocks in northwestern Pennsylvania was of only minor value as a medicine until a technology was developed in the mid-nineteenth century that enabled it to be refined into a lamp illuminant. Some resources that were once valuable are no longer important. For example, it was the availability of pine tar and tall timber—strategic materials valued by the English navy—that in the seventeenth century helped spur settlement in northern New England, but that region now uses its vegetative cover (and natural beauty) as a different type of resource—for recreation and tourism. Resources, therefore, are the result of people seeing a need and perceiving an opportunity to meet that need.

The quantity and quality of a resource is determined by whether it is a renewable, non-renewable, or a flow resource. Renewable resources, such as plants and animals, can replenish themselves after they have been used if their physical environment has not been destroyed. If trees are harvested carefully, a new forest will grow to replace the one that was cut. If animals eat grass in a pasture to a certain level, grass will grow again and provide food for animals in the future, as long as the carrying capacity of the land is not exceeded by the pressure of too many animals. Nonrenewable resources, such as minerals and fossil fuels (coal, oil, and natural gas), can be extracted and used only once. Flow resources, such as water, wind, and sunlight, are neither renewable nor nonrenewable because they must be used as, when, and where they occur. The energy in a river can be used to generate electricity, which can be transmitted over great distances. However, that energy must be captured by turbines as the water flows past or it will be lost.

The location of resources influences the distribution of people and their activities on Earth. People live where they can earn a living. Human migration and settlement are linked to the availability of resources, ranging from fertile soils and supplies of freshwater to deposits of metals or pools of natural gas. The patterns of population distribution that result from the relationship between resources and employment change as needs and technologies change. In Colorado, for example, abandoned mining towns reflect the exhaustion of nonrenewable resources (silver and lead deposits), whereas ski resorts reflect the exploitation of renewable resources (snow and scenery).

Technology changes the ways in which humans appraise resources, and it may modify economic systems and population distributions. Changes in technology bring into play new ranges of resources from Earth’s stock. Since the industrial revolution, for example, technology has shifted from waterpower to coal-generated stream to petroleum-powered engines, and different resources and their source locations have become important. The population of the Ruhr Valley in Germany, for example, grew rapidly in response to the new importance of coal and minerals in industrial ventures. Similarly, each innovation in the manufacture of steel brought a new resource to prominence in the United States, and resulted in locational shifts in steel production and population growth.

Demands for resources vary spatially. More resources are used by economically developed countries than by developing countries. For example, the United States uses petroleum at a rate that is five times the world average. As countries develop economically, their demand for resources increases faster than their population grows. The wealth that accompanies economic development enables people to consume more. The consumption of a resource does not necessarily occur where the resource is produced or where the largest reserves of the resource are located. Most of the petroleum produced in Southwest Asia, for example, is consumed in the United States, Europe, and Japan.

Sometimes, users of resources feel insecure when they have to depend on other places to supply them with materials that are so important to their economy and standard of living. This feeling of insecurity can become especially strong if two interdependent countries do not have good political relations, share the same values, or understand each other. In some situations, conflict over resources breaks out into warfare. One factor in Japan’s involvement in World War II, for example, was that Japan lacked petroleum resources of its own and coveted oil fields elsewhere in Asia, especially after the United States threatened to cut off its petroleum exports to Japan.

Conflicts over resources are likely to increase as demand increases. Globally, the increase in demand tends to keep pace with the increase in population. More people on Earth means more need for fertilizers, building materials, food, energy, and everything else produced from resources. Accordingly, if the people of the world are to coexist, Earth’s resources must be managed to guarantee adequate supplies for everyone. That means reserves of renewable resources need to be sustained at a productive level, new reserves of nonrenewable resources need to be found and exploited, new applications for flow resources need to be developed, and whenever possible, cost—effective substitutes—especially for non-renewable resources—need to be developed.

It is essential that students have a solid grasp of the different kinds of resources, of the ways in which humans value and use (and compete over) resources, and of the distribution of resources across Earth’s surface.
