There are many copper ore deposits around the glove. If copper ore is in such abundance, why is it considered nonrenewable? 2. a. What are strategic minerals?
b. Why are they important to the United States?
c. Give at least two examples of strategic minerals and where they are found?
3. Give three examples of a renewable resource and explain how it provides energy.

Copper is considered non renewable because while It can be recycled and used again, the deposits themselves do not replenish. At least not quickly enough to be considered a renewable resource.

2. A. Strategic minerals are minerals necessary and vital to national defense and the production of wartime equipment, but are also vital for electronic devices and equipment we use everyday. They are in limited supply, hence the need to be used strategically.

   B. These minerals are important to the United States because the U.S is heavily dependent (unfortunately) on foreign trade and goods for domestic supply. They are also critical to the economic and national security of the U.S.

   C. Two examples of Strategic Minerals include copper and platinum. Copper is found in open pit mines like those in Utah, but also just buried underground in huge lumps called nuggets. Platinum is found in thin sulfide layers in certain mafic igneous bodies. Mafic is a type of mineral or rock rich in magnesium and iron.

3. Examples of renewable resources refer to those that replenish relatively quickly over time and include Biomass, Geothermal energy, and Wind energy. Biomass energy provides energy by burning organic material such as wood, sewage, and ethanol (ethanol comes from plants especially corn). Geothermal energy is created by using the heat within the Earth's core through vents in the surface. These vents heat water causing it to boil. The resulting steam powers a turbine that generates electricity. Wind energy is the use of wind to turn turbines that generate electricity. Wind hits the blade of the turbines and the kinetic force causes them to spin, generating electricity.
