tropical rainforest coloring pages
Tropical rainforests are generally found close to the equator. They are usual in Asia, Australia, Africa, South America, Central America, Southern Mexico and on several from the Pacific Islands. Inside the World Wildlife Fundâ€™s biome classification, tropical rainforests are believed a type of tropical wet forest (or tropical moist broadleaf forest) and may also be referred to as lowland equatorial evergreen rainforest. Minimum normal annual rainfall between 1,750 millimetres (69 in) and 2,000 millimetres (79 in) occurs in this climate region. Mean monthly temperatures exceed 18 Â°C (64 Â°F) during all months of the year. Rainforests are home to half of all the living animal and plant species on the planet. Tropical rain forests are called the â€œworldâ€™s largest pharmacyâ€ because over one-quarter of modern medicines originate from its plants. The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible for people and other animals to walk through the forest. If the leaf canopy is destructed or thinned for any reason, the ground beneath is soon colonized by a dense tangled growth of vines, shrubs and small trees known as a jungle.
