Rainforests are thick growths of plants found in very hot, steamy, wet places

around the world.

The areas shaded green on this map of the world are where rainforests can be found.

Why is it called a Rainforest?

The reason it is called a "rain" forest is because of the high amount of rainfall it gets per year.

Rainforests have a rainfall of at least 254 centimetres a year and often get much more.

Why are Rainforests important to us?

They are very important because the plants of the rainforest generate or make most of the Earth’s oxygen.

Interesting Rainforest Fact

Rainforests are found on every continent across the Earth, except Antarctica.

There are two types of Rainforest:1. Temperate Rainforests 2. Tropical Rainforests

Tropical rainforests are found close to the

equator where temperatures and

rainfall are very high all year round.

Temperate rainforests are

found along coasts in the temperate

zone.

A rain forest has four layers.

Emergent Layer

Canopy Layer

Understorey Layer

Forest Floor

Page 7: Rainforest Ppp

Who lives here? Birds, butterflies

and small monkeys live with bats,

snakes and bugs.

Emergent Layer

The emergent layer is very sunny because it

is the very top of a rainforest. Only the

tallest trees reach this level.

Page 8: Rainforest Ppp

Who lives here? Birds, monkeys,

frogs, and sloths, as well as lizards,

snakes and many insects.

Canopy Layer Most trees in the forest grow to the height of the canopy. There are plants that grow in the canopy layer. Their roots don't reach the ground. These are called air plants.

Who lives here? Insects, frogs and

snakes.

Understorey Layer The understorey layer has many vines and dense vegetation. There is not much light in this layer.

Page 10: Rainforest Ppp

Who lives here? Larger animals such as

jaguars, gorillas, leopards, tapirs, tigers and elephants as

well as insects, snakes and lizards.

Forest Floor

The Forest Floor is dark, damp and full of many dead leaves, twigs and dead plants. The forest floor is dark due to the trees above stopping the sunlight from entering the forest.

An area of a rainforest the size of a football field is being destroyed each second.

The trees of a tropical rainforest are so densely packed that rain

falling on the canopy can take as long as 10 minutes to reach the

ground.

Many of the things we have in our homes comes from the

rainforest.

As many as 30 million species of plants and animals live in tropical rainforests.
