Mineral Resources
Minerals are composed of Elements
http://www.youtube.com/watch?v=9D05ej8u-gU Most Astounding Fact Neil DeGrass Tyson
Nebular Hypothesis;
Nebula is composed of
gas and dust composed of the elements needed to form minerals, rocks and life
The unstable giant explodes in
a supernova!
Crab Nebula: remnant of a supernova explosion in 1054
Exploding all of the elements in all directions into the universe
As a massive star nears the end of its life it has fused elements such as carbon, oxygen, magnesium, iron, silicon
Betelgeuse in the constellation OrionIs a red supergiant

Earth’s Mineral Resources• Group investigations on:
1. Renewable/nonrenewable resources; what’s our choices?5 choices for conservation of resources
2. Minerals in common objects that we use everydaypick 2 or 3 objects and list all the minerals that make them up
3. Common mineral ores and their economic impact $$most common, most expensive, countries with most mineral resources
4. The human impact of resources as shown in the movies/mediamovies: Blood Diamond, 33,
5. The Earth System: how are Earth’s spheres impacted?Kings Canyon mine and the 4 spheres
6. How do mineral resources change the land?5 mining processes, difference between mineral reserve and resource
7. Politics of natural resources: EPAReclamation Act of 1977
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
