Explanation:
<h3>Resources are the products of the physical system but they also depend on human ability and need, not by nature. Human beings evaluate the natural environment and classify those substances that provide value to them. Resources are therefore dynamic cultural conceptions.</h3>
Geography's relevance to science and society arises from a distinctive and integrating set of perspectives through which geographers view the world around them. This chapter conveys a sense of what is meant by a geographic perspective, whether it be applied in research, teaching, or practice. Due to space limitations, it does not attempt to cite the many excellent examples of research illustrating geography's perspectives; the citations refer mainly to broad-ranging summaries of geographic research that are intended as resources for further reading.
Taking time to understand geography's perspectives is important because geography can be difficult to place within the family of academic disciplines. Just as all phenomena exist in time and thus have a history, they also exist in space and have a geography. Geography and history are therefore central to understanding our world and have been identified as core subjects in American education. Clearly, this kind of focus tends to cut across the boundaries of other natural and social science disciplines. Consequently, geography is sometimes viewed by those unfamiliar with the discipline as a collection of disparate specialties with no central core or coherence.
