Rain forests

Temperate and tropical rain forests are the two different types of rain forests!

Sadly both are endangered.

Biome description


Tropical Rain forests are located on the equator. On the other hand, Temperate Rain forests are found along coasts in the temperate zone. The largest tropical Rain forest in the world is located in Africa, South America, and Southeast Asia. They can also be found in the Central America Amazon river basin and the Zaire river basin. Those aren't the only places they are found, here are some more: West coast of India, Assam, New Guinea, Madagascar, Malaysia, and Queensland, Australia.

General Characteristics

Tropical rain forests are usually a hot and moist biome. Tropical rain forests are located near the equator. Over 15 million plant and animals species are living within this biome.

Microorganisms and bacteria find the rain forest as a perfect home because of its hot and humid conditions. These organisms quickly decompose matter on the forest floor. The soil is infertile and acidic. The tropical rainforest is included in the tropical wet climate group. Tropical rainforests have more types of trees than any other kind of forests or area in the world. Now, rainforests cover less than 6% of the Earth's surface. The rainforest has been home to many tribes such as the Yanomamo in South America, and Pamagirri in Australia.

Abiotic factors

Weather and Climate

Most tropical Rain forests get about 50 to 260 inches of rain, which is spread out evenly each year. The temperature of the Rainforest never rarely gets hotter than 93 degrees Fahrenheit and no cooler than 68 degrees Fahrenheit. The Rainforest is a very wet and hot place. That us one of the reasons why the plant, animal, and bacteria life is so dense. The Rainforest is almost always wet. The year round humidity is a high 77% to 88%. When the Rainforest rains, it really rains! It can pour as much as 2 inches or rain in an hour.


The Rain forest is a hot place. It's basically summer all the time. The Rainforest may be wet but it is very hot. The temperature in a Rainforest barely ever gets hotter than 93 degrees Fahrenheit and it never gets an cooler than 68 degrees Fahrenheit. There is no winter in the Rainforest and the day light can last for twelve hours. Constant heat for twelve hours.

Thermometer and Hygrometer in the Rainforest.


It rains almost all the time in the Rainforest. It can pour 2 inches or rain in one hour. The humidity level is also very high. The humidity ranges from 77% to 88%. Most tropical Rain forests get 50 to 260 inches of rain year round. The rain is spread evenly throughout the year. That means it doesn't just pour all the rain at the beginning of the year and leave none for the rest of the year.

Rain in the Rainforest



You may not think of a Rainforest like this but there are mountains in Rain forests. One Rainforest sits on a very moist mountain. This kind of Rainforest is called a Montane Rainforest. The Rainforest actually reaches up to the clouds, it is so tall.

Bodies of water

There is obviously going to be a river, lake, stream, something in a Rainforest. If there wasn't one, all the water would just seep into the ground and then the forest would flood. There are some Rain forests though that have that exception. These are called flooding rain forests. The Amazon river runs through most Rain forests on that side of the world.


Believe it or not, rain forests also have canyons. When the rain from the river eroded the rock or ground, it eroded into a canyon. Most of these canyons were created by the Amazon river.


Rain forests have islands too you know. They actual Rainforest itself can be on an island. I mean, where do you think they got all the rain from? Yes, the ocean. Sometimes, the Rainforest will have a beach, sometimes it's just a drop of river.


Rain forests also have Waterfalls. They can be short or tall. Most Rain forests have waterfalls that dump into either a river or a canyon.

Biotic factors


The Rainforest is home to many animals. Including a bunch of rare birds and plants and other animals that we don't usually see in the U.S. One of the birds is the Toucan, one of my favorites. Other animals include the Crested Guan, the Sloth, the Orangoutang, or even a bearded pig.

The Rainforest also has plants that we don't see every day. When a plant grows on the forest floor it doesn't get much sunlight because of the taller plants above. These following plants get about 3% sunlight. Such as, Lianas, Epiphytes, Mangroves, Bromeliads, and Nepenthes.

Ecological concerns or issues

Catastrophic events

Even though you may not believe it, Rain forests can have fires. The probability of a Rainforest having a fire is more likely, due to logging in the canopy layer of the Rainforest.

They can also flood. Flooding isn't caused by loggers though, it is a natural event caused by the height of the land the Rainforest is on, and how much it rains.

Human impact

Although the Rainforest is hot the trees are used for human use. This means the destruction of the Rainforest. They also use the land after cutting down the trees to grow crops and raise animals. The loss of these trees is effecting the Earth's weather system. This is also causing the extinction of rare animals.

Here's a video that covers most everything about a rainforest.
