• Turn in Homework to the
basket.
• Please pick up a world map
• Take out your map pencils.
You will need nine different
colors. 
Objective
•Explain the influence of climate on
the distribution of biomes in
different regions.
Biome: a major regional group of
plants and animals adapted to the
environment (ecosystems).
Two Types of Biomes:
Terrestrial (land)
Aquatic (water)
#1 Tundra: an area where the tree
growth is hindered by low
temperatures and short growing
seasons. Northern most landmass
(Alaska, Canada and Russia)
Tundra
You will find permafrost or
permanently frozen soil in tundra
areas.
Areas of tundra have high winds, little
rain, and temperatures that dip into
–70 degrees.
Tundra tends to be rich in natural
resources like oil and uranium, and
low in animal and plant diversity.
#2 Taiga: cold, northern coniferous
forest (boreal forest)
Taiga
Taiga is the largest biome and a
major supplier of oxygen.
Temperatures barely climb above
freezing in taiga and there is little sun
because it barely climbs above the
horizon.
#3 Grassland: open flat areas of
grass
Grasslands
Areas of grassland have little
precipitation and are plains or low
rolling hills (cover the central region
of most continents).
#4 Deciduous Forest: areas in which
the trees lose their leaves each year.
Deciduous Forest
#5 Chaparral: dense vegetation
consisting of stunted trees or bushes
Chaparral is hot and dry
with common wildfires.
#6 Desert: a dry, often sandy region
of little rainfall and sparse vegetation
Desert
Areas of desert receive less
than 10 inches of rain a year.
#7 Savanna: tropical grasslands with
scattered trees or shrubs
Savanna
Areas of savanna have a long dry
season and a very wet season.
#8 Rainforest: a forest of tall trees,
year round warmth and constant rain
Rainforest
Rainforest cover 6% of the earth but
generate 40% of our oxygen.
#9 Alpine: mountainous
regions which are cold
Alpine
Areas of Alpine are cold because of
elevation (above the tree line).
#10 Coniferous Forest: forest which
keep their leaves all year long.
#11 Coral Reef:
a ridge or
mound made
by colonies of
tiny coral
animals; found
only in shallow
regions of
tropical oceans
Coral Reef

•On your blank world map, color the 9
different biomes.
•In the bottom left corner, create a(n)
index/table of the biome’s color.
•Then, explain in complete sentences
for each biome:
– What is the CLIMATE in this biome and how
does it affect it? P. 70
– What would you wear and what would you do
in your leisure time?
Pre AP Enrichment
• Create a journal entry of someone living in
a specific biome. Describe the climate, how
you dress, what job you would have, and
how you would live. Do NOT include the
name of the biome. Trade with a partner
and let them guess the biome.
