Rain Forests
• Rain Forests have warm temperatures.
• The Rain Forest is the home to more organisms than
any other biome on Earth.
• There are two common types of Rain Forests; the
Temperate Rain Forest and the Tropical Rain Forest.
• Rain Forests are incredibly moist areas.
• Cover about 6% of Earth’s surface.
Temperate Rain Forest
•
•
•
•
Have excessive amounts of precipitation.
Average about 200-350cm of precipitation annually.
The average temperature is 20°C.
Mainly found in regions of South America, New
Zealand and Australia. They are also found on the
Olympic Peninsula in Washington State.
• Plants: Many trees that are found there are Maple,
Birch, Oak, Hickory, Sweet Gum. Those types of trees
are hardwoods which means that they lose their
leaves in the winter.
• Animals: Many animals that are found there are
Squirrels, Bear, Deer, and various species of birds.
Tropical Rain Forest
• The average temperature is 25-29°C and there is very
little season variation.
• The Rain Forest gets 200-400cm of rain yearly.
• This type of Rain Forest is commonly found along the
Tropic of Cancer and the Equator.
• Plants: Bromeliads, Mushrooms, various herbs, Kapok
Tree, and orchids.
• Animals: Many animals found there are various
primates, various species of birds, butterflies, frogs, a
variety of fish and lizards.

Layers of the Rain Forest
The three major layers in the
Rain Forest are …
The Overstory- This
contains a lot of tree’s
tops.
The Canopy- The dense
ceiling of closely
spaced trees and their
branches.
The Understory- There
is a widely space here
that contains smaller
tree species, and
juvenile individuals that
are created underneath
the Canopy Layer.
The Shrub Layer- There
are trees located here
that only grow from 5 to
20 feet.
The Forest Floor- This
is made up of fungus,
trunks of tree’s and
small vegetation.
Human Impact
• Humans have established communities in there.
• Agriculture and development are causing the rain
forest’s to be demolished at a rapid rate.
• People are harvesting the different plants and foods
that are grown in the Rain Forests such as; Avocado,
various woods, Nuts, Guava, Bananas, and Cocoa
Beans.
• Animal habitats are being destroyed due to the impact
of the humans.
Geological Features…
• Rainforests are very wet areas.
• They are usually mountainous areas that
almost always have small or large
waterways flowing through them.
• Rainforests usually have waterfalls or
rivers and streams running through them.
• Rainforests are sometimes flat regions.
