rain forest

A dense evergreen forest with an annual rainfall of at least 160 inches (406.4 centimeters).
Did You Know? Rain forests are, not surprisingly, forests where it rains a lot—between 160 and 400 inches (406.4 and 1,016 centimeters) a year. Most of the world's rain forests lie near the equator and have tropical climates with temperatures that remain around 80°F (26.6°C) all year long. However, there are also cooler rain forests, such as the one in the Pacific Northwest region of the United States and Canada. The largest rain forest in the world is the one located in the Amazon River basin in South America. Rain forests are extremely important because they help regulate the world's climate and because they host such extraordinary diversity of life. Scientists believe that as many as half of the Earth's different species of plants and animals are found only in the rain forests, which take up a mere 7 percent of the world's landmass. Among other benefits, this biodiversity supports important biological research. For example, many of the natural chemicals used in prescription drugs are found in plants that grow only in rain forests. Unfortunately, the demand for agriculture is causing many people to turn rain forests into farms and grazing land, and by some estimates, more than half of the Earth's original rain forests have already been burned or cut down.
