3What makes up a tropical rain forest?
4There are two types
- Tropical rain forests receive more than 80
inches of rain a year. Some rain forests can
receive as much as 200-400 inches of rain a year!
These forests also have large amounts of
humidity, or water vapor in the air.
- Temperate rain forests are forests that have very
distinct seasons and a more moderate climate.
Rain occurs evenly throughout the whole year.
5Rain forest Comparisons
- Tropical
- 200-400 rain per year
- broadleaf on trees
- hundreds of species of trees
- temperature constant around 75ºF
- endangered
- Temperate
- 100 of rain per year
- needle leaves on trees
- 10 - 20 species of trees
- temperature average 60ºF
- endangered
6The climate of a tropical rain forest is very
hot and humid so the animals and plants that
exist there must learn to adapt.
7Where are tropical rainforests located?

9Rain forest layers
In the emergent layer, trees can be 200 feet
high. Most trees are broad-leaved, hardwood
evergreens. Sunlight is plentiful. Animals
found here are eagles, monkeys, bats and
butterflies.
The canopy layer forms a roof over the two
remaining layers and is a very dense layer. The
leaves on most trees are smooth and come to a
point. Food is abundant for animals such as
snakes, toucans and tree frogs.
Little sunshine reaches this layer so the plants
have to grow larger leaves to reach the sunlight.
Plants in this area seldom grow to 12 feet.
Animals that live here include jaguars, red-eyed
tree frogs and leopards and many insects.
This layer is very dark, so no plants grow here,
Things decay very quickly here. A leaf that
might take one year to decompose in a regular
climate will disappear in only 6 weeks. This is
the home for giant anteaters.
10Why are they important?
- These incredible places cover only 6 of the
Earth's surface, but MORE THAN 1/2 of the world's
plant and animal species live there! - At least two-thirds of the world's plant species,
grow in the rain forests.
11In addition
- We eat many foods from the rain forest and many
medicines are made from ingredients found only in
these areas.
- Cinnamon
- bananas
- rubber
- coffee
- cocoa and many more
12 Of the millions of animal species in the world,
over half are found in the rain forest and
nowhere else on Earth.

15People of the Rainforest
People have lived in the rain forests for
thousands of years. They live in harmony with the
forest, plants and animals. Their traditions and
customs are unlike other people.
16Homes in the forest are very different. They
don't need walls on their houses because it
doesn't get cold t here. Natives don't need much
privacy at all. Privacy is a lot different than
what you may be used to and we do go into houses
without asking.
17 Children are expected to do lots of work and
they get up early in the morning. The girls
look after their little sisters, brothers,
nieces, or nephews. They also help cook, grate
manioc, carry heavy backpacks, and get water.
18The boys in the village have to do some work,
too. They fish, farm, and weave baskets with the
men in the village. They also spend much time in
the jungle as part of their learning and training
to become excellent hunters and providers for
their families.
19In their free time, both boys and girls love to
go swimming in the river, and there are plenty of
rivers around in the rain forest. They also like
to watch the animals in their village. The
girls like to play with their hand-made
dolls (since there are no stores around here to
buy them). Boys like to shoot their bows and
arrows and play in the forest.
20Guess who is in the yellow rain coat?
Why is the rain forest so valuable?
21- How has it helped us?
- Fifty percent of the medicines used every day
come from rain forest plants. - The corn plant originally came from the forests
in Mexico and South America. - Rice came in Asian rain forests.
- Orange juice, tea, eggs, and bananas originally
came from Asian rain forests. - Over 50 of the fruits you eat originally came
from tropical rain forests. -

resources...
23What problems are there for the rain forest?
24The Rain Forest is in Trouble In addition to
being one of our most precious natural resources,
tropical rain forests are among the most
endangered habitats on earth because of
deforestation. Causes of Deforestation
clearance for roads and railways
forest fires mining and drilling for
fuel wood international timber
trade collection and clearance for
living space Humans already have destroyed
half of the rain forest area, with most damage
occurring in the last 200 years.
25A delicate ecosystem destroyed
- Rainfall is absorbed by the trees.It is pulled up
to the canopy where it evaporates into the air. - Trees and plants receive most of their nutrients
from decaying matter such as fallen leaves and
organic debris. - Plants and trees hold down the topsoil. This
keeps it from washing away in heavy rains. - When the land is cleared and crops are planted
the soil doesn't stay fertile for long because it
doesn't have nutrients from the decaying matter. - Once plants are removed, heavy rains wash away
the topsoil.
26By Deforestation
27 Rain forests are important to everyone on the
planet-not just to those who live in or near
them. They help control the world's climate.
When the rain forests are burned and cleared,
carbon is released into the atmosphere.Carbon
dioxide in the atmosphere prevents the suns
radiation from escaping back to the atmosphere.
This causes the weather to be much hotter on the
whole planet. (This is called the greenhouse
effect.)
28When the beautiful forest is gone where do the
animals go?
29What is our responsibility to the rain forest?
30Can you help?
31- WATCH OUT FOR OUR EARTH
- WAYS THAT YOU CAN HELP TO SAVE THE RAIN FOREST
- Write letters to your senators or representatives
to let them know that you are concerned about
rain forest destruction. - Ask that they support programs that help protect
tropical areas throughout the world. - Write letters to other organizations that can
help.
32- ANOTHER WAY THAT YOU CAN HELP TO SAVE THE RAIN
FOREST - Go in with some friends and buy an acre of rain
forest. The Nature Conservancy's "Adopt-an-Acre
Program" lets you purchase the protection of an
acre of rain forest in a specific nature preserve.
33 - WATCH OUT FOR OUR EARTH
- MORE WAYS THAT YOU CAN HELP TO SAVE THE RAIN
FOREST - Turn off the lights or TV when you leave a room
- Recycle paper, cardboard, plastic, glass,
metals--everything you can! - Walk or ride your bike instead of driving.
34Think about all the changes that would happen
if we lose the rain forest
35Forest PeopleForest people will lose their
homes, and their culture. Their knowledge of the
forest is also lost .
Last Songbirds The songbirds, which help farmers
in the U.S. by eating insects, will no longer
winter in tropical forests.
Changed ClimateBurning huge areas of rainforest
releases carbon, which causes changes in wind
currents and rainfall around the world.
Undiscovered MedicinesPlants that might provide
new medicines extinct before they can even be
studied.
ExtinctionThousands of species of rainforest
plants and animals will be lost.
36 What will you do about the rain forest now?
37Are you ready to do more exploring?
Here is a website you can use that is really
neat. You are finished with the slide show at
this point.
