2. I. Major Climate Zones
Climate is the average weather
conditions over a long period of time.
Earth is a complex mix of climates.
Geographers identify these climate by
observing:
Temperature
Precipitation
Native plant life
3. I. Major Climate Zones
With these observations we can divide
Planet Earth into fiver basic climate zones:
I. Tropical
II. Temperate
III. Polar
IV. Dry
V. Highland/Mountain
4. I. Major Climate Zones
I. Tropical Climates
Occur near the equator and
the lower latitudes
These climates extend from
the Tropic of Cancer through
the Equator and down to the
Tropic of Capricorn.
This climate tends to be
warm, muggy, and rainy
year-round.
Temperatures average
around 80°F
Rainfall averages between
70-450 inches per year!!!
This is why it is known as the
rainforest.
Monsoons- Seasonal winds
that bring either dry or moist
air
5. I. Major Climates Zones
II. Temperate
Climates
Occur about halfway between
the equator and the poles in
the middle latitudes.
This climate has four distinct
seasons.
Summers are short and hot.
Springs and falls are mild.
Winters are long, cold, and
typically snowy.
Plant Life: Tall grasslands to
both coniferous and deciduous
trees
Main areas in U.S.: Great Plains,
Midwest
6. III. Temperate Climates
This climates tends to have mixed forests.
Deciduous trees
Lose their leaves each fall.
Coniferous trees
Do not shed their leaves and are green year-
round.
7. I. Major Climate Zones
III. Polar Climates
Occur near the
poles
Higher latitudes
Even with this
extreme cold, polar
bears, penguins,
whales, and seals
are able to survive
quite well in this
frigid climate
8. I. Major Climate Zones
IV/V. Dry and Highland
Climates
These can be found in
many different latitudes.
This climate can be
several climates at
once.
It depends upon
elevation.
As you go up the
mountain, temperatures
drop and plant life
grows more scarce.
