Ecozones
An Ecozone is made up of different characteristics
that make this part of Canada different and unique.

Canada’s Climate
• Canada has 8 climate regions
Arctic
Taiga
Cordilleran
Pacific Maritime
Boreal
Prairie
Southeastern
Atlantic Maritime
Canada’s Climate
• There are 6 factors that make Canada’s
climate different.
LOWERN
L = Latitude
O = Ocean Currents
W = Wind
E = Elevation
R = Relief
N = Nearness to Water
L = Latitude:
LOWERN
• The distance (north and south) from the
equator (0o).
• Regions close to the equator are warmer since
direct sun’s rays produce more heat.
• Latitude determines if a region is hot or cold
O = Ocean Currents
• Ocean currents
bring warm or cold
water to new places
• If the ocean current is
warm then it will heat
the air above it.
• If the ocean current is
cold then it will cool
the air above it.
W = Wind:
• Wind moves hot
and cold “air
masses” to other
parts of the world.
• If there is no
wind, our weather
wouldn’t change
very much!
LOWERN
E = Elevation:
LOWERN
• Elevation: refers to the height above sea
level.
• The higher up you are
the colder it gets
R = Relief:
LOWERN
• Relief: refers to physical features such
as mountain ranges
(i.e. big difference in
elevation).
• Mountains act like a
barrier to air masses
N = Nearness to Water:
LOWERN
• Region that are close to
oceans and large lakes
have different climates.
• In the summer  water remains cooler then the
land and when wind blows, it brings cool air over the
land.
•In the winter  water keeps its heat and when wind
blows, it bring warm air over the land.
LOWER
Continental and Maritime
Climates
• A region that is close to a large body of
water (ocean or large lakes) has a Maritime
Climate.
• A region that is NOT
close to a large body of
water has a Continental
Climate.

Maritime Climate
So, Canada has different
Climates because of….
L = Latitude
O = Ocean Currents
W = Wind
E = Elevation
R = Relief
N = Nearness to water
How does climate affect us?
1. A Drought (no rain, very dry period) can destroy
crops and soil.
2. Major snow/rain storms can cause major
transportation problems
3. Climate affects the vegetation, soil and
wildlife (animals).
4. Climate also affects certain industries in
Canada like farming and mining.
Climate Graphs
A Climate Graph
shows the average
temperatures and
precipitation
(rainfall), for each
month for a region or
city.
A Climate Graph should have…
1. Title of
region or city
2. Temperature
(oC) in a red line
5. Average Annual
temperature (oC) &
Total annual
precipitation (mm)
3. Precipitation
(mm) drawn in
blue blocks
4. Months at
the bottom
