Forests where it rains a lot and is very humid. A wide variety or plants and animals live in them, many of which can't be found anywhere else in the world. They're a great ecosystem.

rainforests are forests with tall trees, warm climate, and lots of rain. In some rainforests it rains more than one inch every day

Rainforests are very dense, warm, wet forests. They are havens for millions of plants and animals. Rainforests are extremely important in the ecology of the Earth. The plants of the rainforest generate much of the Earth's oxygen. These plants are also very important to people in other ways; many are used in new drugs that fight disease and illness. Different animals and plants live in different parts of the rainforest. Scientists divide the rainforest into strata (zones) based on the living environment. Starting at the top, the strata are: EMERGENTS: Giant trees that are much higher than the average canopy height. It houses many birds and insects. CANOPY: The upper parts of the trees. This leafy environment is full of life in a tropical rainforest and includes: insects, birds, reptiles, mammals, and more. UNDERSTORY: A dark, cool environment under the leaves but over the ground. FOREST FLOOR: Teeming with animal life, especially insects. The largest animals in the rainforest generally live here. http://www.enchantedlearning.com/subjects/rainforest/

1) "Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). From 40 to 75% of all species on Earth are indigenous to the rainforests. It has been estimated that many millions of species of plants, insects, and microorganisms are still undiscovered. Tropical rainforests have been called the "jewels of the Earth", and the "world's largest pharmacy", because of the large number of natural medicines discovered there. Rainforests also supply 28% of the worlds oxygen, processing it through photosynthesis from carbon dioxide. The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible to walk through the forest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs, and small trees called a jungle. There are two types of rainforest, tropical rainforest and temperate rainforest."

They are common in Asia, Australia, Africa, South America, Central America, Southern Mexico and on many of the Pacific Islands. Within the World Wildlife Fund's biome classification, tropical rainforests are considered 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 °C (64 °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 "world's largest pharmacy" 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 destroyed or thinned for any reason, the ground beneath is soon colonized by a dense tangled growth of vines, shrubs and small trees called a jungle."

Forest in which it Rains always- Sometimes in house also!!!!!!!!!!!!!!!!!!!

where vast amounts of rain is grown, sometimes referred to as a forest of rain, or "rainforest"

The forest in the heavy raining area
