Tropical rainforest

Tropical rainforest
A tropical rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall. Rainforests can be found in Asia, Australia, Africa, South America, Central America, Mexico and on many of the Pacific, Caribbean, and Indian Ocean islands. Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical wet forest (or tropical moist broadleaf forest) and may also be referred to as lowland equatorial evergreen rainforest.[3] Overview[edit] Tropical rainforests can be characterized in two words: hot and wet. Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation as a result of human activity. History[edit] Tropical rainforests have existed on Earth for hundreds of millions of years. Forest floor[edit] Related:  RainforestsRainforestKlimawandel

Rainforest Animals 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

Energy Cities' Annual Conference in Bornova (Izmir), Turkey from 1 to 3 June 2016 Rainforest Concern Facts For a downloadable booklet of rainforest facts and other materials for use in the classroom, please go to Resources for Schools Tropical rainforests - where and what are they? Tropical rainforests are found across the world between the Tropic of Capricorn and the Tropic of Cancer, 22.5° North and 22.5° South of the Equator. Almost half of the remaining tropical rainforest is found in tropical America, a bit more than a third in Asia and Oceania, and fifteen percent in Africa. Tropical rainforests cover approximately 8% of the world’s land surface - an area of approximately 1.2 billion hectares - and yet contain over half of the earth’s species of animals and plants. The largest rainforest, the Amazon, is found in South America and spans nine nations (Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana and Suriname, as well as French Guiana), covering a total area of approximately 600 million hectares.

Tropical Rainforest Where are tropical rainforests found? Tropical rainforests are located around the equator where temperatures stay near 80 degrees year round. Rainforests receive 160 to 400 inches (400-1000 cm) of rain each year. The largest rainforests are in Brazil (South America), Zaire (Africa) and Indonesia (South East Asia). Other tropical rainforest places are in Hawaii and the islands of the Pacific & Caribbean. What is the tropical rainforest? The Tropical Rainforest is a forest occurring in tropical areas of heavy rainfall. What is the structure of vegetation in the rainforest? The image above shows a typical cross section in the rainforest. Emergents are the tallest trees and are usually over 50 metres tall. The sea of leaves blocking out the sun from the lower layers is called the canopy. The under canopy mainly contains bare tree trunks and lianas. The shrub layer has the densest plant growth. The forest floor is usually dark and damp. How did the tropical rainforest get like this? Local: Global:

Example: Campa Pita, Belize Description There are two types of rainforests, tropical and temperate. The tropical rainforest is a hot, moist biome where it rains all year long. Rainforest Rainforests are forests characterized by high rainfall, with annual rainfall between 250 and 450 centimetres (98 and 177 in).[1] There are two types of rainforest: tropical rainforest and temperate rainforest. The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests. Tropical Tropical rainforests are characterized by a warm and wet climate. Many of the world's rainforests are associated with the location of the monsoon trough, also known as the intertropical convergence zone.[7] Tropical rainforests are located in the tropics, i.e., in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn. Temperate Layers A tropical rainforest is typically divided into four main layers, each with different plants and animals adapted for life in that particular area: the emergent, canopy, understorey/understory and forest floor layers.

2016 Temperatures Already Pushing COP21 Limits By Climate Central Coming off of the hottest year on record globally, international leaders met last week in New York to sign the historic Paris Climate Agreement. The agreement endeavors to limit planetary warming by “holding the increase in the global average temperature to well below 2°C (3.8°F) above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C (2.7°F).” However, if the first three months of 2016 are any indication, meeting that challenge will be increasingly difficult. Globally, calculations from both NOAA and NASA indicate that the first three months of 2016 are each more than 1°C above each agency’s baseline average. NOAA uses the 20th century average temperature, and NASA uses the average temperature from 1951-80. Using this method, the NASA/NOAA data indicate that the period of January-March was 1.48°C (2.66°F) above that 1881-1910 baseline. Related Graphics

Rainforest - Reference Rainforests are forests that get a great deal of rain and have extremely diverse wildlife. Rainforests are found in the tropical regions across the Southern Hemisphere, and contain more than 50% of all living species on Earth. Rainforests typically get an average of 1,850mm of rain every year. There are two main types of rainforest habitat, which are the tropical rainforests, and the seasonal rainforests. In fact, the rainforests have a total of 170,000 of the world’s 250,000 known plant species (no less than 68%), according to this infographic about the rainforest. Due to the fact that rainforests all over the world are being cut down, a great amount of effort is now being put into protecting these indigenous tribes by governments, charities and international organisations. The tropical rainforest tends to have various layers of canopy, with the top layer often reaching up to 75 meters in height. There are different animals and plants inhabiting the different rainforest types.

Why Save the Rain Forest? Imagine what it is like to walk through a rain forest. You pass hundreds of trees, many more than 125 feet high. You see orchids, ferns, and other exotic plants growing on tree trunks. Above, sunlight filters through the canopy of leaves, but you are walking in deep shade. You have probably heard how important rain forests are. Why Save the Rain Forests explains how rain forests touch everyone's life. Plants from the rain forest provide us with many other important things. What if there were no more rain forests? Where rain forests have been cleared from the land, much less rain falls.

Tropical rainforest climate Worldwide zones of Tropical rainforest climate (Af). A tropical rainforest climate, also known as an equatorial climate, is a tropical climate usually (but not always) found along the equator. Regions with this climate typically feature tropical rainforests, and it is designated by the Köppen climate classification. Description[edit] Distribution[edit] Upland rainforest in Borneo. A tropical rainforest climate is usually found at latitudes within five degrees North and south of the equator, which are dominated by the Intertropical Convergence Zone. Some of the places that have this climate are indeed uniformly and monotonously wet throughout the year (e.g., the northwest Pacific coast of South and Central America, from Ecuador to Costa Rica, see for instance, Andagoya, Colombia), but in many cases the period of higher sun and longer days is distinctly driest (as at Palembang, Indonesia) or the time of lower sun and shorter days may have more rain (as at Sitiawan, Malaysia).
