19
Q

Smelting

A

20
Q

Commercial Forests

A

Have trees that can be harvested for profit

21
Q

In-stream use

A

Water used without removing it from the lake or river.
Ex: Transportation, Fisheries, Recreation

22
Strip mining
Used to extract minerals such as coal or oil sands that are located in horizontal layers near the surface
23
Coniferous Trees
Cone bearing trees with needle leaves
24
Deciduous Trees
Trees that lose their leaves every year
25
Non-Commercial Forests
Unlikely to be cut down for industrial use
26
Mixed Forests
A forest region with warmer temperatures, longer growing seasons and high precipitation. Types of Trees include Fir and Spruce, Coniferous, Deciduous and Hardwood.
27
Conventional Energy Sources
Commonly used and generally non-renewable sources such as natural gas, coal, hydro and nuclear energy.
28
Consumed Water
Water that is consumed by humans and livestock or "lost" into the atmosphere through evaporation and transpiration.
29
Drainage Basin
An area of land where water from rain or snow melt drains downhill into a body of water such as a river, lake, wetland or ocean.
30
Withdrawal Use
Actual removal of of water from the water body Ex: Agriculture, mining, livestock
31
Non-Withdrawal Uses
Water that is not removed from it's source when it's used. Ex: Hydro-electric generator
32
Wetlands
Swamps, Marshes, Bogs
33
Watershed
An area of land that drains or “sheds” water into a specific water body
34
Sustainability
Our ability to maintain a high quality of life for all people (humans)
35
Hydro Electric Generating Station
Mechanical energy that is produced by moving water
36
Thermal Electric Generating Station
Mechanical energy that is produced by expanding steam by burning coal, oil and natural gas
37
Nuclear Electric Generating Station
Mechanical energy that is produced by expanding steam from nuclear fission
38
Ecological Footprint
A way of measuring the demand we place in the environment
39
Energy Efficient
Appliances, vehicles, etc. that use up less energy than non-efficient supplies.
40
Fair Earthshare
The amount of land people would get if evenly divided.
41
Fossil Fuels
Non-renewable and burned to produce energy. Ex: Oil and natural gas
42
Metallic Mineral
When refined they form metals. Mined for their beauty and rareness. AKA precious metals. Often mined for their strength or other unique properties such as conducting electricity. Ex: Iron, Copper, Gold, Silver, Platinum, Nickel
43
Milling
The beginning process of creating “ore concentrate” where waste rock is removed
44
Mineral
A naturally occurring, pure, non-living substance found in the rocks of the earth.
45
Mineral Reserve
A portion of a mineral resource that is economically mineable
46
Underground Mining
Used to extract mineral ores located deep in the earth. Does the least damage to the environment.
47
Renewable Resource
A resource that replaces itself unless badly mismanaged Ex: Trees grow to replace those cut down or lost to fire or disease; polluted air is cleaned by the environment
48
Non-Renewable Resource
Once they are removed form the earth, they will not be replaced in our life times. - Can be stored for a considerable length of time after being extracted - Most are not living organisms Ex: Mineral resources (oil, gas, coal, copper)
49
Tailings
Water materials from the smelting process - water, chemicals, rock particles) that are poisonous and must be disposed of
