History Of Venezuela
The history of Venezuela reflects events in areas of the Americas colonized by Spain starting 1522; amid resistance from indigenous peoples, led by Native caciques, such as Guaicaipuro and Tamanaco. However, in the Andean region of western Venezuela, complex Andean civilization of the Timoto-Cuica people flourished before European contact. In 1811, it became one of the first Spanish-American colonies to declare independence, which was not securely established until 1821, when Venezuela was a department of the federal republic of Gran Colombia. It gained full independence as a separate country in 1830. During the 19th century, Venezuela suffered political turmoil and autocracy, remaining dominated by regional ''caudillos'' (military strongmen) until the mid-20th century. Since 1958, the country has had a series of democratic governments. Economic shocks in the 1980s and 1990s led to several political crises, including the deadly Caracazo riots of 1989, two attempted coups in 199 ...

Bolivarian Revolution
The Bolivarian Revolution is a political process in Venezuela that was led by Venezuelan President Hugo Chávez, the founder of the Fifth Republic Movement and later the United Socialist Party of Venezuela (PSUV). The Bolivarian Revolution is named after Simón Bolívar, an early 19th-century Venezuelan revolutionary leader, prominent in the Spanish American wars of independence in achieving the independence of most of northern South America from Spanish rule. According to Chávez and other supporters, the Bolivarian Revolution seeks to build an inter-American coalition to implement Bolivarianism, nationalism and a state-led economy. On his 57th birthday, while announcing that he was being treated for cancer, Chávez announced that he had changed the slogan of the Bolivarian Revolution from "Motherland, socialism, or death" to "Motherland and socialism. We will live, and we will come out victorious." As of 2018, the vast majority of mayoral and gubernatorial offices are he ...

Plane (tool)
A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used. Generally, all planes are used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of lumber or timber. Planing is also used to produce horizontal, vertical, or inclined flat surfaces on workpieces usually too large for shaping, where the integrity of the whole requires the same smooth surface. Special types of planes are designed to cut joints or decorative mouldings. Hand planes are generally the combination of a cutting edge, such as a sharpened metal plate, attached to a firm body, that when moved over a wood surface, take up relatively uniform shavings, by nature of the body riding on the 'high spots' in the wood, and also by providing a relatively constant angle t ...

Chopping Tool
In archaeology a chopping tool is a stone tool. Stone tools have been dated using scientific dating such as Carbon 14 dating and Potassium argon dating. Stone tools have been found to be almost 2 million years old. Chopping tools have been found to be about 2 million years old as well. The oldest object in the British Museum is a Chopping Tool. It was found in the Olduvai Gorge The Olduvai Gorge or Oldupai Gorge in Tanzania is one of the most important paleoanthropological localities in the world; the many sites exposed by the gorge have proven invaluable in furthering understanding of early human evolution. A steep-si ... in Tanzania. Since Chopping tools are a sub category of stone tools we can see how these tools have developed over time. Looking at how these tools are made is an important part in the history of the Chopping Tool. A large, hard stone was needed as well as a softer stone that would be made into the chopper. The soft stone was commonly basalt (volcanic rock). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tool
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity of ...

Lithic Flake
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often ( but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion. Since cores are often struck on an edge with a suitable angle (<90°) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Archaeologist
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Ávila National Park
The Ávila National Park, officially known as Waraira Repano National Park for its name indigenous Cariban name, protects part of the Cordillera de la Costa Central mountain range, in the coastal region of central-northern Venezuela. The area's highest elevation is Pico Naiguatá, at above sea level. Culture & traditions El Ávila is known as "el pulmón de la ciudad", the lungs of the city, since it serves many different functions for residents of Caracas, the most basic of these being navigation: the peak of El Ávila marks the north of the city. It is home to the longest cable car ride in the world, as well as activities like running, biking, rock climbing, camping, and zip-lining. El Hotel Humboldt as well as many restaurants, including La Chivera, Casa Pakea, El Jardín de Luna, Le Galipanier, Granja Natalia and Tarahumara, are all nestled in the mountain's hills. Every December, the "Cruz de Navidad" is illuminated, a large crucifix high up in the mountain that faces t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroglyph
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning "stone", and meaning "carve", and was originally coined in French as . Another form of petroglyph, normally found in literate cultures, a rock relief or rock-cut relief is a relief sculpture carved on "living rock" such as a cliff, rather than a detached piece of stone. While these relief carvings are a category of rock art, sometimes found in conjunction with rock-cut architecture, they tend to be omitted in most works on rock art, which concentrate on engravings and paintings by prehistoric or nonliterate cultures. Some of these reliefs exploit the rock's nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Roques Archipelago
The Los Roques Archipelago (Spanish: ''Archipiélago de Los Roques'') is a federal dependency of Venezuela consisting of approximately 350 islands, cays, and islets in a total area of 40.61 square kilometers. The archipelago is located directly north of the port of La Guaira, in the Caribbean Sea. The islands' pristine coral reef attracts many wealthy visitors, especially from Europe, some of whom come in their own yachts and anchor in the inner, protected shallow waters. Development and tourism are controlled. Because of the wide variety of seabirds and rich aquatic life, the Venezuelan government declared Los Roques a National Park in 1972. History Its first settlers were the Caribbean aborigines who visited the islands to collect botutos, fish, hunt turtles and extract salt. There are still some constructions of salt flats with dikes, stone paths and remains of houses that were created at this time known as the time of exploitation of salt. But the permanent occupation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
