STANDARD 3
How to analyze the spatial organization of people, places, and environments on Earth’s surface.
The geographically informed person must understand that physical and human phenomena are distributed across Earth’s surface and see meaning in their arrangements across space. Geography usually starts with questions such as, “Where?” “What is it like here?” and “Why is this located there and not here?” When considering “where” questions, geographers seek regularities—that is, patterns as well as relationships among phenomena (the features of Earth and activities that take place on Earth). They describe and explain patterns in terms of distance, direction, density, and distribution. They use spatial concepts, processes, and models as powerful tools for explaining the world at all scales, local to global.
Spatial concepts provide a language for describing the arrangement of people, places, and environments. Arrangements can be characterized in terms of proximity, distance, scale, clustering, distribution, etc.
Once students start to identify spatial patterns and use maps and remotely sensed images to discover patterns, then they can begin to explore why the patterns and relationships among phenomena exist as they do, that is, what processes produce the patterns. Processes are the driving forces and underlying causes of observable patterns.
Students must understand the mechanisms underlying processes, from the physical activities that shape the environment to the human processes of economic development, urbanization, migration, and cultural change. Models are idealized and simplified representations based on assumptions about reality, and they can help students analyze spatial organization by demonstrating properties of physical and human features, by simplifying the complexity of reality, and by serving as a source of working hypotheses in research. Models can be organized along a continuum from concrete reality (a globe or a diorama) to higher degrees of abstraction and generalization (models of urban structures, spatial interactions, and physical processes).
Understanding these themes and related concepts enables students to explore the patterns of human and physical phenomena and the processes that influence these patterns. Students use models to convey knowledge and generalizations related to Earth’s spatial organization. The use of spatial thinking brings a deeper understanding and appreciation of the complexity and interconnectedness of the physical and human world.

- Construct a model of the community and identify the different land uses (e.g., residential, industrial, retail).
- Construct a model of a watershed linked to a model of the hydrologic cycle and describe its key features and the interconnections to the local water supply (e.g., identify mountains, river systems, lakes, oceans, and groundwater that are a part of the system that supplies water to the local community).
8th Grade
1. The meaning and use of spatial concepts, such as accessibility, dispersion, density, and interdependence
Therefore, the student is able to:
A. Describe the spatial organization of people, places, and environments (where things are in relation to other things) using spatial concepts, as exemplified by being able to
- Describe spatial concepts, such as population density, transportation networks or linkages, and urban or city growth patterns using paper or digital maps.

- Identify and describe service functions along US interstate highways using a digital globe or street-view maps (e.g., shopping malls, service stations, restaurants, hotels).
2. Processes shape the spatial patterns of people, places, and environments over time
Therefore, the student is able to:
A. Describe and compare the processes that influence the distribution of human and physical phenomena, as exemplified by being able to
- Describe how changing transportation and communication technologies influence human distribution and settlement patterns using time lines, maps, and graphs (e.g., compare historic routes West, such as the Santa Fe Trail and Route 66 with current modes and routes of travel and discuss how these have influenced settlement, map the flow of emigrants to the United States by ethnic group, date, factors causing emigration, ports of entry, and settlement patterns, comparing early immigration to current immigration).
- Describe and compare the changes in environmental systems that cause changes in cultural, political, or economic conditions (e.g., a species becoming endangered leads to protected locations and conservation management, climate change influences emissions control legislation, depletion of a natural resource results in higher costs and effects new technologies).
- Describe and compare changes in natural vegetation zones and land uses on the slopes of a mountain (e.g., vertical zonation, tree lines in middle latitudes).
