Terms and Definitions Section pg. 7.1-7.4, 144-147 and 154-159 in text book. Cornell notes on terms. https://youtu.be/LI0Zh_7XUdw Bozman science overview of mineral resources and terms (6:30 min)
Definitions/Cornell Notes Renewable Resources: one that can be replaced in nature at a rate close to its rate of use Nonrenewable Resources: exists in a fixed amount or is used up faster than it can be replaced in nature (MINERALS) *recall that Earth is a CLOSED system Ore Mineral: rock that contains enough of a metallic element to make separation profitable is called an ore; ore mineral is the valuable mineral (metal) that can be separated Examples: iron ore, copper ore Gangue: the rest of the rock that is left from the separation (quartz, feldspar, calcite for example) Mineral Resource: estimates of minerals that are available globally Mineral Reserve: the known deposits of a mineral in ores that are worth mining Surface Mining: this changes the land because it involves digging great holes called open-pit mines; it also removes tons of soil, ore or rock which often creates a rocky waste that supports little life; often what is left barren hills, level mountains, dangerous collections of water/run off, polluntants Purposes of Conservation: protection, restoration and management of natural resources EPA: Environmental Protection Agency-monitors and sets standards for drinking water and air quality
