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

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
