City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain toxic lev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehispanic
In the history of the Americas, the pre-Columbian era spans from the original settlement of North and South America in the Upper Paleolithic period through European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures. Many pre-Columbian civilizations were marked by permanent settlements, cities, agriculture, civic and monumental architecture, major earthworks, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European colonies (c. late 16th–early 17th centuries), and are known only through archaeological investigations and oral history. Other civilizations were contemporary with the colonial period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own wri ...

Obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, granting them a high viscosity. The high viscosity inhibits atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejido
An ''ejido'' (, from Latin ''exitum'') is an area of communal land used for agriculture in which community members have usufruct rights rather than ownership rights to land, which in Mexico is held by the Mexican state. People awarded ejidos in the modern era farm them individually in parcels and collectively maintain communal holdings with government oversight. Although the system of ''ejidos'' was based on an understanding of the preconquest Aztec calpulli and the medieval Spanish ejido, in the twentieth century ejidos are government-controlled. After the Mexican Revolution, ''ejidos'' were created by the Mexican state to grant lands to peasant communities as a means to stem social unrest. As Mexico prepared to enter the North American Free Trade Agreement in 1991, President Carlos Salinas de Gortari declared the end of awarding ejidos and allowed existing ejidos to be rented or sold, ending land reform in Mexico. Colonial-era indigenous community land holdings In central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans-Mexican Volcanic Belt
The Trans-Mexican Volcanic Belt ( es, Eje Volcánico Transversal), also known as the Transvolcanic Belt and locally as the (''Snowy Mountain Range''), is an active volcanic belt that covers central-southern Mexico. Several of its highest peaks have snow all year long, and during clear weather, they are visible to a large percentage of those who live on the many high plateaus from which these volcanoes rise. History The Trans-Mexican Volcanic Belt spans across Central-Southern Mexico from the Pacific Ocean to the Gulf of Mexico between 18°30'N and 21°30'N, resting on the southern edge of the North American Plate. This approximately 1000 kilometer long, 90–230 km broad structure is an east–west, active, continental volcanic arc; encompassing an area of approximately 160,000 km2. Over several million years, the subduction of the Rivera and Cocos plates beneath the North American Plate along the northern end of the Middle America Trench formed the Trans-Mexican Vol ...

Náhuatl
Nahuatl (; ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about Nahua peoples, most of whom live mainly in Central Mexico and have smaller populations in the United States. Nahuatl has been spoken in central Mexico since at least the seventh century CE. It was the language of the Aztec/Mexica, who dominated what is now central Mexico during the Late Postclassic period of Mesoamerican history. During the centuries preceding the Spanish and Tlaxcalan conquest of the Aztec Empire, the Aztecs had expanded to incorporate a large part of central Mexico. Their influence caused the variety of Nahuatl spoken by the residents of Tenochtitlan to become a prestige language in Mesoamerica. After the conquest, when Spanish colonists and missionaries introduced the Latin alphabet, Nahuatl also became a literary language. Many chronicles, grammars, works of poetry, administrative docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Río Grande De Santiago
The Río Grande de Santiago, or Santiago River, is a river in western Mexico. It flows westwards from Lake Chapala via Ocotlán through the states of Jalisco and Nayarit to empty into the Pacific Ocean. It one of the longest rivers in Mexico, measuring up long. Geography The river begins at Lake Chapala via Ocotlán and continues roughly north-west through the Sierra Madre Occidental, receiving the Verde, Juchipila, Bolaños, Huaynamota, Mololoa, and other tributaries. The Río Grande de Santiago descends over 1700 meters between Lake Chapala and the sea. Downstream from Lake Chapala the river and its major tributaries have carved deep narrow canyons, or barrancas, which can be 600 meters lower than the surrounding plateau. The lower elevation and year-round moisture in the canyon bottoms sustain forests, which include many coastal tropical species not found on the plateaus. The Barranca de Oblatos or Barranca de Huentitán is a protected area popular with residents of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toltec
The Toltec culture () was a Pre-Columbian era, pre-Columbian Mesoamerican culture that ruled a state centered in Tula (Mesoamerican site), Tula, Hidalgo (state), Hidalgo, Mexico, during the Epiclassic and the early Post-Classic period of Mesoamerican chronology, reaching prominence from 950 to 1150 CE. The later Aztec culture saw the Toltecs as their intellectual and cultural predecessors and described Toltec culture emanating from Tollan, ''Tōllān'' (Nahuatl language, Nahuatl for Tula) as the epitome of civilization; in the Nahuatl language the word ''Tōltēkatl'' (singular) or ''Tōltēkah'' (plural) came to take on the meaning "artisan". The Aztec oral tradition, oral and pictographic tradition also described the history of a Toltec Empire, giving lists of rulers and their exploits. Modern scholars debate whether the Aztec narratives of Toltec history should be given credence as descriptions of actual historical events. While all scholars acknowledge that there is a lar ...

Quetzalcoatl
Quetzalcoatl (, ; Spanish: ''Quetzalcóatl'' ; nci-IPA, Quetzalcōātl, ket͡saɬˈkoːaːt͡ɬ (Modern Nahuatl pronunciation), in honorific form: ''Quetzalcōātzin'') is a deity in Aztec culture and literature whose name comes from the Nahuatl language and means "Precious serpent" or " Quetzal-feathered Serpent". In the 17th century, Ixtlilxóchitl, a descendant of Aztec royalty and historian of the Nahua people, wrote, "Quetzalcoatl, in its literal sense, means 'serpent of precious feathers', but in the allegorical sense, 'wisest of men'." Among the Aztecs, whose beliefs are the best-documented in the historical sources, Quetzalcoatl was related to gods of the wind, of the planet Venus, of the dawn, of merchants and of arts, crafts and knowledge. He was also the patron god of the Aztec priesthood, of learning and knowledge. Quetzalcoatl was one of several important gods in the Aztec pantheon, along with the gods Tlaloc, Tezcatlipoca and Huitzilopochtli. Two other gods re ...
