Characteristics That Defines The Tropical Rainforest Geography Essay

Tropical rain forests are located some distance around the equator and it is one of the Earth ‘s dramatic admirations. It runs from the tropic of malignant neoplastic disease in the northern side of the equator to tropic of Capricorn in the southern portion of the equator. Examples of largest known tropical rain forests are found in Brazil ( South America ) , South East Asia, Indonesia ( islands near the Indian Ocean ) , and Democratic Republic of Congo ( Africa ) , and in the Caribbean Islands ( Isaac and William, 2007 ) . The largest tropical rain forest is the Amazon rainforest found in the South America and which covers about two tierces of the United States continent ( Malhi and Philips, 2000 ) . Tropical rain forests are defined by their wet clime status in that it receives 400 to 760 centimeter of rainfall each twelvemonth as observed by Morecroft and Keith ( pp 298 ) . The clime consists of uninterrupted warm temperatures, high humidness and high rainfalls. Its temperatures range between 25 to 30 Degrees Celsius. This paper will look at the clime that exists in the tropical rain forest and how it affects the growing of a assortment of workss in the tropical rain forest.

The tropical rain forests made is made up of largely wet seasons and its climatologic parts lie within the inter-tropical convergence zone. The different types of rain forests are categorized harmonizing to the different types of conditionss they experience during the twelvemonth and sing their geographical location ( Osterndort et al, 2001 ) . These rain forests includes the monsoon, semitropical and the equatorial type. The rain is experienced about every twenty-four hours and it lies between 1500 to 2500mm throughout the twelvemonth. The temperatures vary during the twenty-four hours and dark in that during the twenty-four hours, the temperatures range between 30 to 35 grades Celsius while during the dark, the temperature drops to between 19 and 24 grades Celsius. The type of clime experienced in the tropical rain forest is the equatorial clime and it is characterized by high comparative humidness runing from 77 % to 88 % and this supports a assortment of works species ( Martinelli et al, pp 1107 ) .

The tropical rain forest is filled with green veggies throughout the seasons because of the high rate of rainfall which encourages growing of trees that form canopies which provide shadiness to other workss and animate beings populating in the country. The ambiance is ever humid, hot and moist due to the canopies that are formed from the trees. The rain forest provides a place to different types of animate beings and contains many species of workss more than any other type of flora countries known. Its clime has no pronounced summer and winter in that the temperature differences between the twenty-four hours and dark is observed to be larger than the differences in temperature between summer and winter.

The climatic features that defines the tropical rain forest includes mean day-to-day temperature of around 27 grades Celsius, the diurnal temperature alteration is between 2 and 5 grades Celsius, the latitude comes under the stagnations low force per unit area belt all the twelvemonth unit of ammunition, the rainfall is normally convection Al and eventually the noon Sun is ever near the perpendicular and is overhead twice a twelvemonth at the equinoxes. The rainforest dirts are non normally fertile and this is because the uninterrupted rains wash off the valuable foods. The day-to-day conditions rhythm of the tropical rain forest begins in the forenoon when the Sun radiances, heats up the land doing hot and wet air rise in the ambiance so in the afternoon, the dark clouds brings the rain and electrical storms in the rain forest and this rhythm is repeated continuously each twenty-four hours ensuing to an of all time wet country ( Lewis, 2006 ) .

The rain forest is made up four beds viz. ; the emergent bed, the canopy, the understory and in conclusion the workss that make up the forest floors. First, the emergent bed consists of a little figure of trees that are tall which is referred to as ‘Emergents ‘ . The trees grow above the canopy that is has been created by the other trees and ranges to a tallness of about 54m. These trees are adapted to defy strong air currents and high temperatures from the direct sunshine. It is normally in habited by bird of Joves, monkeys, chiropterans and some butterflies.

Second, we have the canopy bed which besides consists of tall trees of height 45m maximally. The canopy is estimated to incorporate an about 50 % of different works species as it has been discovered to be the densest country of biodiversity. It contains epiphytic workss which attach themselves to corner short pantss and subdivisions for support. These workss besides obtain H2O and mineral salts from rain and dust that is collected from the other back uping workss in the canopy part ( Schneider and Root, pp 710 ) .

Third, we have the understory bed which is located in the part between the forest floor and the canopy. These country forms a home ground to serpents, lizards, leopards, boa constrictors, birds and other marauders. The part does non have plenty sunlight due to the canopy bed above it in that about, the under narrative receives 5 % of entire sunshine. It is sometimes referred to as a bush bed ‘ . The last bed is the forest floor which is estimated to have merely 2 % of sunshine. The country is characterized by low floras because of the comparatively low sunlight incursion and lone workss that are adapted to low light survive in this part. The rate of decay in workss and carnal affair are sped up by the handiness of warm and humid conditions. The presence of Fungis besides speeds up the rate of decay of workss and animate beings.

For many old ages it was thought that workss in the tropical rain forest were unaffected by the equatorial clime but recent surveies indicated that the warm temperatures of tropical rain forest affected the growing of a assortment of workss in the part. Lewis ( pp 198 ) , stated that the desiccant conditions in the cloud wood could take to extinction of some species of workss more particularly the orchids. He besides monitored tree growing, tropical temperatures and degree of C dioxide released as a consequence of high humidness and warm clime. His researches on the affair revealed that the tropical rain forest trees gave off more C dioxide than they could utilize and this resulted to a alteration in the composing of wood. He besides noted that the trees at times grew at a slower rate when the darks were warm. Other surveies by Osterndort et Al ( 2001 ) indicated that some trees grew at a faster rate when the degree of C dioxide rose while other tree types declined in verve.

Lewis ( pp 200 ) , indicated that an addition of C dioxide in the tropical rain forest was the chief ground for the disconnected displacements in species growing and this, he noted, could take to serious ecological reverberations in the country sing these.

The type of clime experienced in the tropical rain forest has made workss turning in the country to accommodate themselves so that they can last the bing conditions such as growing of shrubs and canopies. Examples of such workss and how they have adapted themselves includes ; lianas which have thick vines that loops around the bole of trees to make the top and receive sunshine. Normally their roots come in different forms and changing length. Their life begins from the forest floor but they grow upwards depending on trees for support until they reach to the top of the tall trees. When they reach at the top, they so spread towards other lianas and trees and injure themselves tightly so that they can be in a place to resists strong air currents.

Another type of works in found in the warm environment of tropical rain forest is the fern. The ferns turn in the forest floor as they are good adapted to last on such a status. Apart from these, we besides have the air plants or air workss which perch themselves high on the subdivisions as they become detached from the land. They begin their life from the canopy from seeds taken at that place by air current or birds. Some of the tallest trees have buttress roots system which ensures entire stableness against strong air current and to increase the surface country under which they obtain their foods from ( Morecroft and Keith, 2009 ) .

The diverseness in works species is said to be highest in the tropical rain forest part and it is the duty of persons to guarantee that the trees are maintained to let growing of these trees. Tropical rain forest is reported to keep a clear environment that is safe for human stay in that it uses up all the C dioxide in the air and releases a clean ambiance.


Conclusively, it has been observed from the above that the equatorial clime in the tropical rain forest favours the growing of a assortment of works species. It is noted that the tropical rain forest is the largest ecological country that supports and gives a home ground to a diverseness if workss and animate beings. The climatic alterations have been observed by Malhi and Philips ( 2000 ) , to be unchanging and are characterized by high degrees of rainfall and high humidness. The climatic status has created the outgrowth of different beds which contains a assortment of works species doing it one of the Earth ‘s most dramatic scenery.
