|Organization:||United States Geological Survey (USGS)|
|Summary:||Because the formation of soil involves the interaction of numerous physical, chemical, and biological processes, the study of soil provides an unmatched opportunity to illustrate connections between science and a systems approach to understanding earth processes. Soil, as the basis for agriculture, is one of the most important mineral resources of a nation. Throughout history, civilizations have prospered or declined as a function of availability and productivity of soils. Few topics in the science curriculum can illustrate so well the relevance, importance, and human dependence upon earth resources. Students separate, examine and identify the major components of soil to better understand how these components give soil its unique physical characteristics.|
