What is strip-mining?
A mining technique that involves removing the topsoil and rock to access minerals or coal deposits near the Earth's surface.
How do humans impact mineral distributions?
Humans impact mineral distributions through activities such as mining.
What are some common uses for the burning of fossil fuels?
Fuel cars, heat our homes, power electricity plants
What happens to fresh water when wells are overdrawn?
Fresh water can become contaminated.
What are at least 3 examples of minerals we learned about being extracted?
Iron Ore, Aluminum Ore, Phosphate rock, Chromium, Copper, Manganese, Zinc, Lead, Nickel, Tin, Cobalt, Silver, Gold, Titanium Concentrates, Glowstone
Why is conservation important today?
As the human population grows, more people on Earth use more and more resources. There must be a better balance between the human need to use resources and the conservation and protection of existing resources
If the cost of separating a mineral from waste rock becomes too great, the mineral may no longer be classified as an ore. This happens because ____.

What is permeability?
a material's ability to allow fluids (like water or gas) to flow through it
Why do you think the life expectancy of different mineral reserves varies?
The projected life of mineral deposits are based on reserve estimates and current production rates.
What is one reason that total depletion of resources has not occurred?
Total reserves have increased, Geologists have improved their ability to locate new reserves, Technological advances = more economical to extract
What is an ore?
A rock with a high concentration of a valuable mineral
Why do fossil fuels generate more power than wood for use in machines, for example?
They are significantly more energy-dense, meaning that a smaller amount of fossil fuel can produce a larger amount of energy than an equal amount of wood.
