What do you picture when you hear the term rainforests?  Do you think of a hot, steamy, wet area with lots of trees?  Let's learn about rainforests!

 

What is a rainforest?

Rainforest

There are two types of rainforests, tropical and temperate.

Tropical rainforests are forests that receive more than 80 inches of rain a year.  Some rainforests receive as much as 200-400 inches of rain a year!  Rainforests also have large amounts of humidity, or water vapor in the air.
 

Temperate rainforests are forests that have distinct seasons and moderate climate. The rain occurs evenly throughout the year.

Look at the chart below to compare tropical and temperate rainforests.

Where are rainforests located?

World map of rainforests

Tropical Rainforests are located near the equator, between the Tropic of Cancer and the Tropic of Capricorn.  Over 1/2 of the tropical rainforests are located in Latin America. About 1/3 of earth's tropical rainforests are located in Brazil, in South America.

Temperate Rainforests are usually located along coastlines.  The largest temperate rainforest is located along the western coast of North America.

 

Why are rainforests endangered?

Rainforests are being destroyed at an alarming rate.  About 6% of Earth's land is rainforest land. Humans are using rainforest land to build their homes on, farm, or sell the wood. Only 3% of the original temperate rainforests remain. Scientists estimate that 50 million acres of rainforest land are being destroyed every year.

 

Why are rainforests important?

  • Rainforests are home to about half of the plant and animal species on Earth.

  • There are still many plant species that have not been discovered.

  • Approximately 1/4 of medicines come from rainforest plants.

  • Many of the foods we eat originated in the rainforests: bananas, avocado, oranges, papaya, paprika, peanuts, pineapple, rice, to mention a few.

  • Rainforests help maintain global rain and weather patterns.

It is very important to try to SAVE THE RAINFORESTS.
