Q

whats the difference between a renewable and non renewable resource

A

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

22
Q

name 3different types of industry

whats the fourth ?

A

primary-extractive resources/industries
secondary- manufacutring industries
teritary- service industries
quaternery industries ex: technology (apple)

23
Q

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

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)

24
Q

describe hydro-electric power plants

A

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.
25
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)
26
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
27
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
28
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
29
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 ```
30
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 ```
31
name 3 aternative enrgy sources
wind solar tidal
32
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
33
4 major import categories
high tech products goods produced in warmer climates \ motor vehicle parts low cost goods
34
3 main export categories
products based on our natural resources motor vehicles specialized manufactured goods
35
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
