5.9
Elements that conduct electricity, heat and have structural properties for building (found within ores)
What is metals?
A resource that is replenished naturally
What is a renewable resource?
Biomass that are easily gathered and purchased (used in developing nations)
What are subsistence fuels?
Biomass fuel sources that are easily accessible. Often used in developing countries as a home heating or cooking fuel
What are subsistence fuels?
Bitumen deposits where crude oil can be recovered, but with higher water and energy inputs
What are tar/oil sands?
The process of removing large portions soil and rock to access ore underneath
What is surface mining?
This rate must be below the rate of regeneration for resources to be renewable
What is the rate of consumption
These nations use more energy on a per capita basis
What are developed nations?
Crude oil is extracted by this method
What is drilling?
Coal takes this long to form
What is 100-150 years?
A resource contaminated by acid mine drainage
What is water?
These will run out because they take far longer to regenerate than the rate we use them
What are fossil fuels?
The second-largest source of energy worldwide
What is hydroelectric energy?
This is the majority of natural gas
What is methane?
This country has the largest oil sands reserve
What is Canada?
What is subsurface mining?
These resources do not run out if overused
What are nondepletable renewable resources?
As developing nations develop the consumption of this will increase
What are fossil fuels?
Coal is formed from pressure from overlying rock and sediment layers compacting this into coal over time
What is peat?
The country with the fourth-largest oil reserves
What is Canada?
Identify a common technique used in mining for minerals such as gold and copper
What is open-pit mining?
Describe one environmental benefit associated with an offshore wind project
What is reduced environmental damage from decreased reliance on fossil fuels?
Explain how electricity is generated at hydroelectric dams
What is: the water moves towards the turbines, rotating them, turning the generator, which is converted to electricity?
Describe a benefit of burning natural gas as opposed to other fossil fuels
What is natural gas releases less CO2, sulfates, and particulates?
Describe the geological features associated with natural gas reserves
What is gas rich shale?
