Renewable vs. Nonrenewable
Natural Resources
Copper is specifically valuable because of what properies?
It is a good conductor of heat and electricity.
Fossil fuels, such as petroleum are extracted through water process and where?
- Drilled Oil Wells
- Petroleum is specifically extracted from under ancient bodies of water.
What term describes leftover material after valuable substances are recovered rom ore?
Waste or Byproduct
What is the name for a rock containing economically valuable concentrations of metals or other minerals?
Ore
A resource that can be replaced as quickly as people use it, such as wood when new trees are planted is called what?
Renewable
What resource is used to make many products, provide heat for buildings and fuel for vehicles?
Petroleum
A country uses 2.5 billion shoes each year for 330 million people. What is the per capita consumption of shoes in this country?
About 7.6 shoes per person each year
What is resource use divided by the number of people called?
per capita consumption
What method uses underground shock waves and records reflected water to reveal buried structures?
Seismic Reflection
Petroleum, coal and natural gas are formed from ancient remains and are examples of what?
Nonrenewable resources
What condition descibes a resource that is not plentful and can make it vaulable?
Its scarcity/rarity
What chemical was added to malachite to extract the copper?
Sulfuric Acid
What is on environmental impact of copper mining?
Fossil fuels can form in ancient wetlands or seas, gold can be deposited by rivers, and some metal deposits are related to volcanic activity. What do these clues help explain about deposits?
Resource deposits are unevenly distributed around the earth.
Freshwater is renewable through the water cycle. But why do some places have much less available than others?
Resources are unevenly distributed around the world.
What technology and exploration methods may companies need to use to search for less accessible deposits?
In Activity 5: Extracting Resources, the Flambeau Mine was explored as it was opened and then closed after producing tons of gold, silver and copper. What was the primary negative consequence of this mining operation?
Waste from the mine is now leaking into the riving.
What is one way to reduce the environmental impact of copper mining.
- Recycling existing copper
- Find alternative ways to conduct heat/electricity that reduces the use of copper
- Require safer mining practices
*can't just say, mine less*
A company uses geologic evidence to locate a copper deposit, then mines ore and uses sulfuric acid, iron, and heat in a modeled process to recover copper. What is one likely environmental concern linked to the process?
Water contamination or waste byproduct
Why is providing fresh water to the world's population challenging?
97% of the earth's water is Salt water.
Of that remaining 3% only 0.03% is found in lakes/ponds. The rest is underground of stored as ice in glaciers.
Diamonds: hardness/density and/or beauty
Fresh water: usefulness (needed to sustain life)
The chemical reaction with malachite and sulfuric acid produces a copper substance, water and carbon dioxide. How did we observe the carbon dioxide?
The gas bubbles poduced
How can a country have a high per capita consumption of a resource, such as copper, yet not have any copper mines present?
The country still requires the resource and must import it from a mine somewhere else.
Metals, such as copper, silver and zinc are often associated with what underground geologic feature?
Magma or past past volcanic activity
