Document Summary
Env100: module 6 session 61 and 62 (minerals and mining) Critical flow resources (effectively non-renewable because of mismanagement) Other (e. g. , human resources, indigenous ecological knowledge) Living resources replace or restock themselves by births and growth . Some energy resources (e. g. , biofuels) (sunlight, tidal, hydro, etc. are technically inexhaustible) Living population stocks can be mismanaged to the point where the population crashes irretrievably. Some replenishable resources can become effectively non-renewable . Renewable and regenerating in principle, but on a long time scale (e. g. , groundwater, soil) Earth"s resources are extracted from the solid earth . Rocks provide the mineral resources we need . Rock = solid aggregation of minerals, tightly compacted or held together by cement-like material or by interlocking grains. Mineral = naturally occurring solid inorganic chemical element or compound with a crystal structure, a specific chemical composition, and distinct physical properties. Oil even from a naturally occurring seep like this is not a mineral.
