• 6.1 Climates and Biomes
• 6.2 Deserts and Grasslands
• 6.3 Temperate Forests and Rainforests
• 6.4 Taigas and Tundras
6.3 Temperate forests
• Temperate deciduous
forests are found in
middle-latitude regions
where there are 4
distinct seasons.
• The word deciduous
means these trees lose
their leaves the end of
the growing season.
6.3 Temperate forests
• Rainfall is enough to support oak, beech,
maple, basswood, cottonwood, and
willow trees.
• These trees have broad leaves.
6.3 Tropical rainforests
• Tropical rainforests are found near the
equator— rainfall here averages at least
200 cm. per year.
• Because rainforests are near the equator,
the temp. averages 23oC year round.
6.3 Tropical rainforests
• According to NASA data, an area of
tropical rainforest the size of North
Carolina is destroyed every year.
• Land is cleared for crops, grazing, lumber,
or firewood.
• When clear-cutting occurs here, the thin
topsoil soon washes away, making the
region useless for agriculture.
6.3 Tropical rainforests
• Brazil nuts, bananas,
pineapple, cocoa,
coffee, vanilla and
cinnamon flavorings,
and coconut come
from tropical
rainforests.
6.3 Temperate rainforests
• Like temperate
deciduous forests,
temperate rainforests
are found in the middlelatitude regions.
• Temperate rainforests
are cool and sometimes
covered in fog.
This temperate rainforest is • Fog provides more
moisture for the plants.
found in coastal areas of
the Pacific Northwest.
