Rainforests for kids What are the different layers of a Rainforest Called? There are four main parts of a Rainforest. They are: Emergent Layer - very sunny because it is the very top. Only the tallest trees reach this level. Who lives here? Canopy Layer - much of the rain is stopped by the thick foliage. Understory Layer - many vines, dense vegetation, not much light. Forest Floor - dark, damp, full of many dead leaves, twigs and dead plants. Click here to find out more
Tropical Rain Forest As you can see from the map to the right, the tropical rainforests are, indeed, located in the tropics, a band around the equator from 23.5 N (the Tropic of Cancer) to 23.5 S (the Tropic of Capricorn) (red lines on map, right). Because the Earth tilts 23.5 degrees on its axis as it travels around the sun, at some point in the year (the solstices, June 22nd in the north, December 22nd in the south) the sun will be directly overhead on one of these lines. At the equinoxes the sun is directly over the equator. Within this band, solar radiation is most intense, and thus the surface of the planet warms the most. The warmth leads to a lot of evaporation, and as warm, moist air rises, it cools, the water condenses, and the water falls back to the earth as rain. Thus, the warmest areas of the planet also tend to be the wettest, and this sets the stage for the tropical rain forest. Not all of the land in the tropics is tropical rainforest.

BBC Nature - Rainforest videos, news and facts Interesting Facts Rainforest Biomes The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. Rainforests now cover less than 6% of Earth's land surface. A tropical rain forest has more kinds of trees than any other area in the world. About 1/4 of all the medicines we use come from rainforest plants. All tropical rain forests resemble one another in some ways. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species. Layers of the Rainforest There are four very distinct layers of trees in a tropical rain forest. Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Plant Life Besides these four layers, a shrub/sapling layer receives about 3 % of the light that filters in through the canopies. Animal Life
Climate Rainforest Animals Plants Interesting facts Animals The Plants of the Rainforest A tropical greenhouse More than two thirds of the world's plant species are found in the tropical rainforests: plants that provide shelter and food for rainforest animals as well as taking part in the gas exchanges which provide much of the world's oxygen supply. Rainforest plants live in a warm humid environment that allows an enormous variation rare in more temperate climates: some like the orchids have beautiful flowers adapted to attract the profusion of forest insects. Competition at ground level for light and food has lead to evolution of plants which live on the branches of other plants, or even strangle large trees to fight for survival. The aerial plants often gather nourishment from the air itself using so-called 'air roots';. The humidity of the rainforest encourages such adaptations which would be impossible in most temperate forests with their much drier conditions.
