Summary

Understanding the origin and utilization of economic geological resources has relied on many of the concepts from earlier chapters.
Geology is the key to understanding,

1. How mineral resources and fossil fuels are formed.
2. Where these resources are likely to be found and how they are extracted.
3. Distinguishing between nonrenewable and renewable resources

Synthesis

An understanding of geologically useful materials and resources provides a context for understanding current political and economic and environmental issues.
