Nasca Culture
The Nazca culture (also Nasca) was the archaeological culture that flourished from beside the arid, southern coast of Peru in the river valleys of the Nazca, Rio Grande de Nazca drainage and the Ica Valley.''The Nasca'' by Helaine Silverman and Donald A. Proulx. Blackwell Publishers. Malden. 2002. Strongly influenced by the preceding Paracas culture, which was known for extremely complex textiles, the Nazca produced an array of crafts and technologies such as ceramics, textiles, and geoglyphs. They are known for two extensive construction projects that would have required the coordination of large groups of laborers: the Nazca Lines, immense designs in the desert whose purpose is unknown, and puquios, underground aqueduct (water supply), aqueducts for providing water for irrigation and domestic purposes in the arid environment. Several dozen still function today. The Nazca Province in the Ica Region was named for this people. History Time frame Nazca society developed during t ...

Early Intermediate
This is a chart of cultural periods of Peru and the Andean Region developed by John Rowe and Edward Lanning and used by some archaeologists studying the area. An alternative dating system was developed by Luis Lumbreras and provides different dates for some archaeological finds. Most of the cultures of the Late Horizon and some of the cultures of the Late Intermediate joined the Inca Empire by 1493, but the period ends in 1532 because that marks the fall of the Inca Empire after the Spanish conquest. Most of the cut-off years mark either an end of a severe drought or the beginning of one. These marked a shift of the most productive farming to or from the mountains, and tended to mark the end of one culture and the rise of another. The more recent findings concerning the Norte Chico civilization are not included on this list, as it was compiled before the site at Caral was investigated in detail.

Prosopis Pallida
''Prosopis pallida'' is a species of mesquite tree. It has the common names kiawe () (in Hawaii), huarango (in its native South America) and American carob, as well as "bayahonda" (a generic term for ''Prosopis''), "algarrobo pálido" (in some parts of Ecuador and Peru), and "algarrobo blanco" (usually used for '' Prosopis alba''). It is a thorny legume, native to Colombia, Ecuador and Peru, particularly drier areas near the coast. While threatened in its native habitat, it is considered an invasive species in many other places. The kiawe is a spreading bush or moderately sized tree, bearing spines, spikes of greenish-yellow flowers, and long pods filled with small brown seeds. It is a successful invasive species due to its ability to reproduce in two ways: production of large numbers of easily dispersed seeds, and suckering to create thick monotypic stands that shade out nearby competing plants. It survives well in dry environments due to a long taproot which can reach deep wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramid
A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with a square base and four triangular outer surfaces, is a common version. A pyramid's design, with the majority of the weight closer to the ground and with the pyramidion at the apex, means that less material higher up on the pyramid will be pushing down from above. This distribution of weight allowed early civilizations to create stable monumental structures. Civilizations in many parts of the world have built pyramids. The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla. For thousands of years, the largest structures on Earth were pyrami ...

Huacas
In the Quechuan languages of South America, a huaca or wak'a is an object that represents something revered, typically a monument of some kind. The term ''huaca'' can refer to natural locations, such as immense rocks. Some huacas have been associated with veneration and ritual. The Quechua people traditionally believed every object has a physical presence and two ''camaquen'' (spirits), one to create it and another to animate it. They would invoke its spirits for the object to function. ''Huacas'' in Peru Huacas are commonly located in nearly all regions of Peru outside the deepest parts of the Amazon basin in correlation with the regions populated by the pre-Inca and Inca early civilizations. They can be found in downtown Lima today in almost every district, the city having been built around them. Huacas within the municipal district of Lima are typically fenced off to avoid graffiti. ''Huacas'' along ceremonial routes A huaca could be built along a processional ceremonial line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nazca Valley
Nazca (; sometimes spelled Nasca; qu, Naska) is a city and system of valleys on the southern coast of Peru. It is also the name of the largest existing town in the Nazca Province. The name is derived from the Nazca culture, which flourished in the area between 100 BC and AD 800. This culture was responsible for the Nazca Lines and the ceremonial city of Cahuachi. They also constructed additional underground aqueducts, named puquios, in a regional system that still functions today. The first puquios are believed to have been built by the preceding Paracas culture. Nazca is the capital of the Nazca Province located in the Ica District of the Ica region of Peru. Earthquake On November 12, 1996, at 11:59 a.m. local time (16:59 GMT) there was an earthquake of magnitude 7.5 with its epicenter at 7.7 km into the sea. The earthquake almost completely destroyed the city of Nazca and its surroundings. Due to its occurrence during the day, there were only 14 fatalities. How ...

Fertility
Fertility is the capability to produce offspring through reproduction following the onset of sexual maturity. The fertility rate is the average number of children born by a female during her lifetime and is quantified demographically. Fertility is addressed when there is a difficulty or an inability to reproduce naturally, which is referred to as infertility. Infertility is widespread, with fertility specialists available all over the world to assist mothers and couples who experience difficulties having a baby. Human fertility depends on factors of nutrition, sexual behaviour, consanguinity, culture, instinct, endocrinology, timing, economics, personality, way of life, and emotions. Fertility differs from fecundity, which is defined as the ''potential'' for reproduction (influenced by gamete production, fertilization and carrying a pregnancy to term). Where a woman or the lack of fertility is infertility while a lack of fecundity would be called sterility. Demography I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mound
A mound is a heaped pile of earth, gravel, sand, rocks, or debris. Most commonly, mounds are earthen formations such as hills and mountains, particularly if they appear artificial. A mound may be any rounded area of topographically higher elevation on any surface. Artificial mounds have been created for a variety of reasons throughout history, including habitation (see Tell and Terp), ceremonial (platform mound), burial (tumulus), and commemorative purposes (e.g. Kościuszko Mound). Archaeology North American archaeology In the archaeology of the United States and Canada, a mound is a deliberately constructed elevated earthen structure or earthwork, intended for a range of potential uses. In European and Asian archaeology, the word "tumulus" may be used as a synonym for an artificial hill, particularly if the hill is related to particular burial customs. While the term "mound" may be applied to historic constructions, most mounds in the United States are pre-Columbian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area, built-up area or urban agglomeration is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of earlier predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be genera ...

Cahuachi
Cahuachi, in Peru, was a major ceremonial center of the Nazca culture, based from 1 AD to about 500 AD in the coastal area of the Central Andes. It overlooked some of the Nazca lines. The Italian archaeologist Giuseppe Orefici has been excavating at the site for the past few decades. The site contains over 40 mounds topped with adobe structures. The huge architectural complex covers 0.6 sq. miles (1.5 km2) at 365 meters above sea level. The American archeologist Helaine Silverman has also conducted long term, multi-stage research and written about the full context of Nazca society at Cahuachi, published in a lengthy study in 1993. Scholars once thought the site was the capital of the Nazca state but have determined that the permanent population was quite small. They believe that it was a pilgrimage center, whose population increased greatly in relation to major ceremonial events. New research has suggested that 40 of the mounds were natural hills modified to appear as ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiefdoms
A chiefdom is a form of hierarchical political organization in non-industrial societies usually based on kinship, and in which formal leadership is monopolized by the legitimate senior members of select families or 'houses'. These elites form a political-ideological aristocracy relative to the general group. Concept In anthropological theory, one model of human social development rooted in ideas of cultural evolution describes a chiefdom as a form of social organization more complex than a tribe or a band society, and less complex than a state or a civilization. Within general theories of cultural evolution, chiefdoms are characterized by permanent and institutionalized forms of political leadership (the chief), centralized decision-making, economic interdependence, and social hierarchy. Chiefdoms are described as intermediate between tribes and states in the progressive scheme of sociopolitical development formulated by Elman Service: ''band - tribe - chiefdom - state''. A ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
