Tropical Rainforests
By: Ghanim Al Naimi 6D
What is the Tropical Rainforest?
Tropical rainforests are located around the equator
from the Tropic of Cancer in the north, to the
Tropic of Capricorn in the south. The largest
rainforests are in Brazil (South America),
Democratic Republic of Congo (Africa), and
Indonesia (islands found near the Indian Ocean).
Other tropical rainforests lie in Southeast Asia,
Hawaii, and the Caribbean Islands. The Amazon
rainforest in South America is the world’s
largest, covering an area about two-thirds the
size of the continental United States.
Temperature
The temperature in a rain forest rarely gets
higher than 93 °F (34 °C) or drops below 68 °F
(20 °C); average humidity is between 77 and
88%; rainfall is often more than 100 inches a
year.

Animals that live in the rainforest
Sloth
The sloth is one of
the most fascinating
animal that inhabit
the rainforests of
South and Central
America. It lives in
the rainforest
because there are
many trees that help
him for his survival.
Toucan
There are about 40
different kinds of
toucans. They vary
in size from about
7 inches to a little
over two feet. They
have short and
thick necks.
Toucans are
distinguished by
large, colorful, yet
lightweight bills.
Spider
Monkey
Spider monkeys are large in
size. Adult monkeys grow to be
almost two feet tall excluding
the tail. They have a powerful
tail that they use as an extra
limb. Spider monkeys like to
hang upside-down with all four
limbs and the tail holding on to
branches which makes them
look like a spider and thus their
name.
Plants in the rainforest
Carnivorous Plants
This plant grows
to 30 feet tall
and may have
pitchers 12
inches in length,
usually
crammed full of
digested insects.
Orchids
Orchids comprise
one of the most
abundant and
varied of flowering
plant families.
There are over
20,000 known
species and
orchids are
especially common
in moist tropical
regions.
Lianas
Ninety per cent of the
world's vine species grow
in tropical rainforests.
Lianas are a type of
climbing vine found
throughout tropical
rainforests. They have
thick, woody stems and
come in various lengths
(up to 3,000 ft) and
varying shapes.
Important Abiotic Factors
The tropical rainforest biome has a very warm and wet climate. It
has an average temperature of 20-34 degrees Celsius . Because
this biome is located very close to the equator, it has very little
seasonal change in temperature or the length of a day. In this
location, it has more direct sunlight hitting land and sea than
most other areas. This makes it very good for the growth of
plants. The sun warms the land and sea and the water evaporates
into the air. The warm air can hold a lot of water vapor. As this
warm air rises to meet the cooler air above the earth's surface,
condensation takes place as the air is cooled down
Resourses
Medical plant (Cocoa tree): The cocoa tree produces more
than 150 chemicals in its leaves, seeds, fruit, and bark.
The Olmecs, Mayans, and Aztecs used parts from the
tree to treat anxiety, fever, fatigue, and coughs. Five
hundred years ago the plant was brought to Europe,
where it was used to treat kidney stones and cuts and
burns, among other things
Interactions
Cocoa Tree: The cocoa tree affects money by
making chocolate and sweets out of the cocoa
tree and selling it at shops and places. It helps
the environment because it doesn't harm any
thing and anyone. This tree affects the
environment by people making food out of
this tree and eating.
Human Activities
Human activities people do in the tropical
is that they can go hunting for animal. Or
they can go looking around and camping
in the Tropical rainforest.
