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.

Explanation:

the wasp’s stinger - protection against predators

the peacock’s bright plumage - attraction to obtain a mate

the owl’s large eyes - help to search for food

the bear’s fur - maintain homeostasis

Explanation:

An adaptation can be define as any change that occurs in the morphology, physiology and genetic make up of the organism which makes it suitable for survival in it's natural environment even in adverse conditions and reproduce.

The following are the adaptations with their benefits.

the wasp’s stinger - protection against predators

The wasp stinger generally exhibit toxic substance or allergy causing agent which the wasp use when it finds a predator around it.

the peacock’s bright plumage - attraction to obtain a mate

The male peacock exhibit bright and showy feathers which is a phenotypic advantage for attraction of female mates for copulation. This phenomena is called as sexual selection.

the owl’s large eyes - help to search for food

The owl's large eyes allows the night vision. There are many rods and cones present in the eyes of the owl so as to allow better vision in night and allow it to observe and capture prey.

the bear’s fur - maintain homeostasis

The bear's fur are insulating in nature that means it does not allow the entry of external air. Hence, helps in retaining the heat in the body in otherwise cold environment. Therefore, helps in maintaining the homeostasis (the tendency of the body retain it's constant internal environment as compared to changing external environment).
