Sierra De Lema
The Sierra de Lema is an upland mountain range area with tepuis, located in Bolívar state of southeastern Venezuela. The names Sierra Rinocote and Sierra Usupamo have historically been applied to its eastern and western portions, respectively. Geography The Sierra de Lema is geologically part of the Guayana Shield, and biogeographically part of the Guayana Highlands. Lying north of the Gran Sabana, it marks the drainage divide between the Caroní River and Cuyuni River drainage basins. It is partly within the bounds of Canaima National Park Torres, I.N. & D.D. Martín (November 2007). Mejorando Nuestra Herencia. and encompasses a number of prominent tepuis, including the entire Los Testigos chain and Ptari Massif. The elevational range of the Sierra de Lema is around above sea level.Huber, O. (1995). Geographical and physical features. In: P.E. Berry, B.K. Holst & K. Yatskievych (eds.)

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Guayanan Highlands Moist Forests
The Guayanan Highlands moist forests (NT0124) is an ecoregion in the south of Venezuela and the north of Brazil and in Guyana, Suriname, French Guiana. It is in the Amazon biome. It encompasses an upland region with diverse fauna and flora, which contains dramatic tepuis, or sandstone table mountains. The region has been inaccessible in the past and is generally fairly intact, apart from the north and northeast where large scale agriculture, ranching and mining operations are steadily encroaching on the ecosystem. New roads are opening the interior to logging, and planned dams will have a drastic impact on the riparian zones. Location The ecoregion includes parts of southern Venezuela, western and southern Guyana and northern Brazil, with scattered portions in Suriname and French Guiana. It extends into eastern Colombia. It has a total area of . The ecoregion lies on the Guiana Shield, an ancient upland area between the Amazon and Orinoco basins. It is surrounded by lowland grass ...

Old-growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ...

Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...

Cerro Venamo
Mount Venamo ( Spanish: ''Cerro Venamo'') is a mountain in South America that forms part of the international boundary between Guyana and Venezuela. The mountain is high and is the westernmost point in Guyana. The mountain is named after the Venamo River, which flows nearby. It is often wrongly synonymized with Waukauyengtipu, a different tabletop mountain within the territory of Guyana, situated approximately 25km southeast of Mount Venamo. Nomenclatural inaccuracies A mountain in Guyana named Waukauyengtipu Waukauyengtipu (or Waukauyeng-tipu, meaning "the mountain of the place of the butterfly" in the local Indigenous Arekuna language) is a mountain in South America situated in most part within the boundaries of the Paruima territory in the Cuyuni-Ma ... is often mistakenly synonymized with Mount Venamo, yet they are separate plateaus and each should be recognized by their respective, separate names. Most of the information about the true location and elevation of Cerro Ven ...

Toponymy
Toponymy, toponymics, or toponomastics is the study of ''toponyms'' (proper names of places, also known as place names and geographic names), including their origins, meanings, usage and types. Toponym is the general term for a proper name of any geographical feature, and full scope of the term also includes proper names of all cosmographical features. In a more specific sense, the term ''toponymy'' refers to an inventory of toponyms, while the discipline researching such names is referred to as ''toponymics'' or ''toponomastics''. Toponymy is a branch of onomastics, the study of proper names of all kinds. A person who studies toponymy is called ''toponymist''. Etymology The term toponymy come from grc, τόπος / , 'place', and / , 'name'. The ''Oxford English Dictionary'' records ''toponymy'' (meaning "place name") first appearing in English in 1876. Since then, ''toponym'' has come to replace the term ''place-name'' in professional discourse among geographers. Toponym ...

Flora Of The Venezuelan Guayana
''Flora of the Venezuelan Guayana'' is a multivolume flora describing the vascular plants of the Guayana Region of Venezuela, encompassing the three states south of the Orinoco: Amazonas, Bolívar, and Delta Amacuro. Initiated by Julian Alfred Steyermark in the early 1980s, it was completed after his death under the guidance of Paul E. Berry, Kay Yatskievych, and Bruce K. Holst. The nine volumes were published between 1995 and 2005 by Timber Press and Missouri Botanical Garden Press. The project brought together more than 200 botanists from around the world and was "the first effort to produce a comprehensive inventory and identification guide for the plants of such an extensive region of northern South America". Volumes The first volume, written primarily by Italian ecologist Otto Huber, is an introduction to the geography, ecology, botanical history and conservation of the Venezuelan Guayana, and includes two fold-out maps of the region (one vegetation and one topographic ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...
