THE RAINFOREST

Rainforests are very dense, warm, wet forests. They are havens for millions of plants and animals. Rainforests are extremely important in the ecology (the relationships between a group of living things and their environment) of Earth. The plants of the rainforest generate much of Earth's oxygen.

CONTINENTS

The continents of South America, Africa, and Asia are homes of the earth's rainforests.

MOISTURE

The rain forest is nearly self-watering. Plants release water into the atmosphere through a process called transpiration. In the tropics, each canopy tree can release about 200 gallons of water each year. The moisture helps create the thick cloud cover that hangs over most rain forests. Even when not raining, these clouds keep the rain forest humid and warm.

LAYERS OF THE RAINFOREST

The temperature, the amount of sunlight, the wetness, and the amount and type of plant and animals differ in each layer of the rainforest.
