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
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.
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.
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.
