Geographic knowledge is critical when faced with a challenge based on changes in the natural environment. For example, the rise in sea levels that scientists attribute to global warming can be tracked with sensors on satellites. Scientists can then assess the future risk of floods for a coastal population based on observed trends.
Analyzing the significance of location requires basic knowledge about a place. Location can be both absolute (i.e., longitude and latitude) and relative (i.e., where a place is in relation to other places). Global positioning systems (GPS) like those you use for driving directions find your absolute position by plotting your location at the intersection of imaginary spheres (picture a Venn diagram) generated by signals of several satellites and then placing that location on a stored map. The relative location of oil fields, for example, makes roads or waterways that access the resources more significant.
Places have both physical and cultural characteristics that blend to reflect the unique nature of a place. For example, physical features might include its landforms and water, weather, soil, and native plants and animals. The culture of a place is determined by a variety of factors: the population, settlement patterns, and race and ethnicity of the people, as well as their languages and religions, economy, architecture, material culture, and politics.
The interaction of people with their natural environment is influenced by their cultural values. For example, European settlers who came to North America treated the land differently than the Native Americans who had lived on it for generations. Some Pennsylvanians who have farmed for generations are choosing to keep their land as pasture while people who work for energy companies are seeking permission to drill wells on that same land in search of natural gas.
Movement or spatial interactions can be political, economic or cultural in nature. The migration patterns of certain immigrant groups to and across the United States may be viewed from a local angle or from a wider international perspective. The delivery of goods and services found in the grocery store may be physical or electronic and may originate from any place in the world.
The concept of regions allows geographers to subdivide the world into manageable areas of focus. The reason why a region is distinctive can include cultural, historical or physical factors and can change as current events realign political and economic relationships amongst countries.

Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
