Nazca 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 of which still function today. The Nazca Province in the Ica Region was named for this people. History Time frame Nazca society develope ...

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
''Neltuma pallida'' (formerly ''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. Description 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pyramid
A pyramid () is a structure whose visible surfaces are triangular in broad outline and converge toward the top, making the appearance roughly a pyramid in the geometric sense. The base of a pyramid can be of any polygon shape, such as triangular or quadrilateral, and its surface-lines either filled or stepped. A pyramid has the majority of its mass closer to the ground with less mass towards the pyramidion at the apex. This is due to the gradual decrease in the cross-sectional area along the vertical axis with increasing elevation. This offers a weight distribution that allowed early civilizations to create monumental structures.Ancient civilizations in many parts of the world pioneered the building of pyramids. The largest pyramid by volume is the Mesoamerican Great Pyramid of Cholula, in the Mexican state of Puebla. For millennia, the largest structures on Earth were pyramids—first the Red Pyramid in the Dashur Necropolis and then the Great Pyramid of Khufu, bot ...

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-Inka and Inka 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; possibly from ) is a city and system of valleys on the southern coast of Peru. The city of Nazca is the largest 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. However, 1,5 ...

Fertility
Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. The fertility rate is the average number of children born during an individual's lifetime. In medicine, fertility refers to the ability to have children, and infertility refers to difficulty in reproducing naturally. In general, infertility or subfertility in humans is defined as not being able to conceive a child after one year (or longer) of unprotected sex. The antithesis of ''fertility'' is infertility, while the antithesis of ''fecundity'' is sterility. Demography In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to produce which is termed fecundity. While fertility can be measured, fecundity cannot be. Demographers measure the fertility rate in a variety of ways, which can be broa ...

Mound
A mound is a wikt:heaped, heaped pile of soil, earth, gravel, sand, rock (geology), 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 topography, topographically higher elevation on any surface. Artificial mounds have been created for a variety of reasons throughout history, including habitation (see Tell (archaeology), 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 earthworks (engineering), 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 ...

Urban Area
An urban area is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlet (place), hamlets; in urban sociology or urban anthropology, it often contrasts with natural environment. The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BCE led to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment. Recent historical growth In 1950, 764 million people (or about 30 percent of the world's 2.5 billion people) lived in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural ...

Cahuachi
Cahuachi, in Peru, was a major ceremonial center of the Nazca culture, based from about in the coastal area of Peru's 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 (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 preceding and during major ceremonial events. New research has suggested that 40 of the mounds were natural hills modified to appear as artifici ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chiefdoms
A chiefdom is a political organization of people represented or governed by a chief. Chiefdoms have been discussed, depending on their scope, as a stateless, state analogue or early state system or institution. Usually a chief's position is based on kinship, which is often monopolized by the legitimate senior members of select families or 'houses'. These elites can form a political-ideological aristocracy relative to the general group. Chiefdoms and chiefs are sometimes identified as the same as kingdoms and kings, and therefore understood as monarchies, particularly when they are understood as not necessarily states, but having monarchic representation or government. 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, ch ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and 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 irrigation, is the olde ...

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), 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 Solvation, 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 Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...
