subject: Rainforests Are Forests Which Are Catagorized By Heavy Rainfall. [print this page] The Intertropical convergence zone plays a major role in creating the tropical rainforests on Earth.
This intertropical convergence zone is the area enclosing the earth near the equator where winds originating in the northern and southern hemispheres come together.
Tropical rainforests are also known as Jewels of the earth and Worlds largest pharmacy. Read more Kronisk hovedpine
Over one quarter of worlds natural medicines are initiated in rainforests. 40%-75% of all species on earth are native to the rainforests.
Though Oxygen is not produced as it is widely misunderstood. The rainforests are liable for 28% of the worlds Oxygen turnover.
Many areas of rainforests lack sunlight at ground level which limits the undergrowth of rainforests.
A solid tangled growth of vines, shrubs and small trees will create a jungle if the leaf covering of the ground of a rainforest is destroyed or thinned.
There are two types of rainforests such as tropical rainforests and temperate rainforests.
Although tropical rainforests have been called the lungs of the earth, it is at present known that rainforests contribute little net Oxygen additions to the atmosphere through photosynthesis. Read more Spisesteder Vejle
Rainforests are common in Asia, Australia, Africa, South America, Central America, Mexico and various of the pacific islands. Tropical rainforests also could be referred to as lowland equatorial evergreen rainforests.
Moderate rainforests are coniferous or broadleaf forests that occur in the temperate zone and receive high rain fall. Warm temperate rainforests receive over 1300 mm rainfall each year.
Temperate rain forests are also called moss forests. While it is not raining, rain forests are often misty.
Rainforests are endangered by human activities. Temperate rainforests take several hundred years to mature and thus fires pose a lasting danger. Rainforests are been cleaned to use the land for farming, or cultivating or mining. Since rainforest timber is famous for its beauty, there is a huge demand for it.
It is not economical to grow rainforest trees in plantations for timber, as they grow very slowly.
A tropical rain forest can be separated in to four main layers. Each of these layers has different plants and animals which are altered for life in these areas. The four layers of the tropical rainforest are the Emergent, canopy, understory and the forest floor. Read more Energiruder pris
In the Emergent layer Eagles, butterflies, monkeys and bats live. A large tree which is called emergent grows here. These trees grow over the general canopy, reaching heights of 45-55 m.
