Document Summary
Cell phones and other tech use mineral resources such as tantalum. Many ways to classify resources, i. e. 1. Earth resocurces are non living and are extracted from the earth replisnhable resources are: replinshable in principal, but long on a time scale ie groundwater, soil replinshable resources are susceptible to mismangament in practice. We live in a closed system but earths resources are very large. The static lifetime is the lifetime expectancy of a resource at current rates of production and use and is hard to calculate rock is a solid aggregation of minerals. Mineral is a naturally occurring solid chemical element or inorganic compond with a crystal structure, a specific chemical composition and distinct physical properties. Glass is a liquid that has been quick frozen. Mineral resources can be metals or non metals. Much more money is made from non metals compared to metals ( ie salt, clay, uranium vs gold, silver)
