The Rainforest
The Rainforest
True to their name, rainforests receive an incredible amount of rain. About 60 inches of
rain falls every year in an average rainforest. Some very wet rain forests can receive up to
400 inches of rain. Temperatures in a rainforest range from 70 to 85, but it can get much
warmer. The temperature in a rainforest rarely drops below 70 at night.
The constant moist and warm conditions in the rainforest allow an astounding variety of
plants to thrive. On a single acre of rainforest, you may find about ten times as many tree
species as a forest in a temperate region.
The rainforest covers less than ten percent of the Earth's land, yet contains more than
90 percent of all of it's animal and plant species. Rainforests contain great treasures, such
as countless species of plants and animals, oil, rubber, precious metals, and much, much more.
Many of these resources already benefit the human race, in the form of medicines, food, and
industrial products, and many are yet to be discovered. Most rainforests are along the
Equator, where the temperatures are the warmest on Earth year round.
Most of the plants and animals that live in the rainforest live nowhere else in the world.
