unit 3- managing canadas resources and industries Flashcards
alternative energy
non-conventional energy source such as solar wind and biomass energy
conventional energy
energy well established source of energy such as oil,natural gas,hydro and nuclear electricity
ecological footprint
measure of total impact on an ecosystem
shelterwood logging
method of logging often used in forests with trees of uniform age and size , that clear cuts parts of a forest leaving some seed bearing trees to regenerate
net import
amounts of which the imports of a commodity (e.g.: stereo equiptment) are greater than the exports of a commodity
trade deficit
situation in which a country has brought more goods or services than it has sold in exports
tree line
boundary between tundra and boreal forest zone. north of this is too cold for trees to grow.
basic industry
industry that sells its products outside the community , bringing money into the community.
biomass industry
energy produced by combusting biomass materials such as wood and manure
fair earthshare
measurement of productive land use in the world by dividing by # of people in the world. this is how much productive land each person would be entitled to, if we all sed the earth equally
stewardship
the management of resources in a careful and sustainable way
net export
amount by which the exports of a commodity (wheat) are greater than the imports of commodity
import substitution
process by which you reach foreign produced goods with canadian ones to support canadian business
sustained yield forest management
use of forest resource at a rate that allows the forest to renew itself
clear cutting
logging method whereby all trees in an area are cut at one time (except small)
carrying capacity
number of ppl that could be supported at current living standards by Canadas productive land
selective cutting
lumbering technique that only certain trees in an area, thats a specific size and quality are cut.
trade surplus
situation where a country has brought in less goods than sold in exports
tariff
tax charged on goods imported into a country to protect local industries from foreign competition.
multiplier effect
total effect on the economy caused by an expansion or contraction in 1 part of it
whats the difference between a renewable and non renewable resource
renewable- replaces itself within a human lifetime unless badly damaged ex: forest , fisheries, solar energy
non renewable- can only be used once, takes too long to replenish ex: coal, natural gas,nuclear energy
name 3different types of industry
whats the fourth ?
primary-extractive resources/industries
secondary- manufacutring industries
teritary- service industries
quaternery industries ex: technology (apple)
where would you find
a) codfish and lobster
b) wood used to produce lumber and plywood
c) wood used to produce paper
d) metallic minerals such as cold nickel copper and silver
e) fossil fuels such as oil and natural gas
f) grains such as wheat,rye,barley and canola
a) codfish and lobster-Atlantic coast
b) wood used to produce lumber and plywood-BC
c) wood used to produce paper-Northern ON, northern QB
d) metallic minerals such as cold nickel copper and silver- Canadian shield
e) fossil fuels such as oil and natural gas-praries
f) grains such as wheat,rye,barley and canola-praries(Saskatchewan)
describe hydro-electric power plants
hydro= water ( fast flowing up-stream)
- renewable
- operatable w/no fuel
- water goes thru penstock, to turbines which turns generators , finally goes into trail trace.
describe thermo-electric power plants
thermoelectricity
- shorter transmission lines
- water runs thru hot pipes
- uses steam rather than moving water
- heat for boiler is produced by burning fuel (coal oil natural gas wood garbage)
Describe nuclear power plants
nuclear electricity
- energy where its needed (transmission costs r low)
- doesnt produce air pollutiion
- water is boiled (steal cools to water)
- reactor core w/uranium fuel is stored under neath steam tank
name the conventional energy source(s) to the place
a) BC-
b) Alberta
d) Nova Scotia
e) Newfoundland
a) BC- hydro
b) Alberta-thermo
c) Ontario - all 3 (abundance of energy)
d) Nova Scotia-thermo
e) Newfoundland - thermo
Hydro advantages and dissadvantages
advantages
- no pollution
- running =cheap
- no fuel needed
- uses renewable resource
disadvantages
costly to build
far from where needed
dams may cause flooding and ruin animals homes
thermo advantages and dissadvantages
advantages
less expensive
built where needed
shorter transmission lines
disadvantages oil,natural gas and coal (non renewable) -global warmer fuel costs--> oil/natural gas
nuclear advantages and dissadvantages
advantages
operating costs are low
no pollution
low transmission costs
disadvantages expensive radiation kills ppl more use,less reliable radiations alive for 1000's of yes
name 3 aternative enrgy sources
wind
solar
tidal
provide reasons why canada uses so much energy
- industrial economy uses energy
- ITS CHEAP aka waste
- transportation energy used
- we live in a cold climate
4 major import categories
high tech products
goods produced in warmer climates \
motor vehicle parts
low cost goods
3 main export categories
products based on our natural resources
motor vehicles
specialized manufactured goods
why must canada import goods
-cannot grow certain foods
- cheaper to produce things in other countries (low labour costs)
- highly specialized industries ( cell phones )
Canada doesn’t wanna compete with South Korea or Japan
