Balberta
Balberta is a major Mesoamerican archaeological site on the Pacific coastal plain of southern Guatemala, belonging to the Maya civilization. It has been dated to the Early Classic period and is the only known major site on the Guatemalan Pacific coastal plain to have exposed Early Classic architecture that has not been buried under posterior Late Classic construction. The site was related to the nearby site of San Antonio, which lies to the west. Balberta first appears to have been occupied in the Late Preclassic period, when it was a small site of minor importance. After a period of rapid growth it became one of the largest Early Classic sites on the Guatemalan Pacific coast and reached the height of its power between AD 200 and AD 400, after which it rapidly declined and was replaced by a new capital at the nearby site of Montana. It traded with the distant metropolis of Teotihuacan in the Valley of Mexico, with other recovered artifacts having their origin on the Gulf coast ...

Montana (Mesoamerican Site)
Montana is a Mesoamerican archaeological site on the Pacific coastal plain of southern Guatemala. It is located in the department of Escuintla, near Balberta, and is one of the largest Mesoamerican archaeological sites on the Pacific Coast of Guatemala. History Around AD 400, in the Early Classic period, Montana replaced Balberta as the regional capital. The investigating archaeologists consider that Montana was founded as a colony by the great metropolis of Teotihuacan in the distant Valley of Mexico in order to supply that city with locally produced products such as cacao, cotton and rubber and to provide a trade route to the great highland city of Kaminaljuyu and to the Maya lowlands across the Sierra Madre de Chiapas.Sharer & Traxler 2006, pp.289-290. The establishment of the Teotihuacan colony at Montana resulted in the collapse of the important nearby site of Balberta and the new capital flourished until about AD 600, dominating the region for about 200 years.

Mesoamerica
Mesoamerica is a historical region and cultural area in southern North America and most of Central America. It extends from approximately central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica. Within this region pre-Columbian societies flourished for more than 3,000 years before the Spanish colonization of the Americas. Mesoamerica was the site of two of the most profound historical transformations in world history: primary urban generation, and the formation of New World cultures out of the long encounters among indigenous, European, African and Asian cultures. In the 16th century, Eurasian diseases such as smallpox and measles, which were endemic among the colonists but new to North America, caused the deaths of upwards of 90% of the indigenous people, resulting in great losses to their societies and cultures. Mesoamerica is one of the five areas in the world where ancient civilization arose independently (see cradle of civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaminaljuyu
Kaminaljuyu (pronounced ) is a Pre-Columbian site of the Maya civilization that was primarily occupied from 1500 BC to AD 1200. Kaminaljuyu has been described as one of the greatest of all archaeological sites in the New World by Michael Coe, although its remains today – a few mounds only – are far less impressive than other Maya sites more frequented by tourists. When first mapped scientifically (by E. M. Shook over a period of decades from the 1930s on), it comprised some 200 platforms and pyramidal mounds, at least half of which were created before the end of the Preclassic period (250 AD). Debate continues about the size, scale, and degree by which, as an economic and political entity, it integrated both the immediate Valley of Guatemala and the Southern Maya area. The known parts of Kaminaljuyu lie on a broad plain beneath roughly the western third of modern Guatemala City. The Valley of Guatemala is surrounded by hills that culminate in a string of lofty volcanoes t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Puebla
Puebla ( en, colony, settlement), officially Free and Sovereign State of Puebla ( es, Estado Libre y Soberano de Puebla), is one of the 32 states which comprise the Federal Entities of Mexico. It is divided into 217 municipalities and its capital is the city of Puebla. It is located in East-Central Mexico. It is bordered by the states of Veracruz to the north and east, Hidalgo, México, Tlaxcala and Morelos to the west, and Guerrero and Oaxaca to the south. The origins of the state lie in the city of Puebla, which was founded by the Spanish in this valley in 1531 to secure the trade route between Mexico City and the port of Veracruz. By the end of the 18th century, the area had become a colonial province with its own governor, which would become the State of Puebla, after the Mexican War of Independence in the early 19th century. Since that time the area, especially around the capital city, has continued to grow economically, mostly through industry, despite being the scene o ...

Zaragoza, Puebla
Zaragoza is a municipality in the Mexican state of Puebla. Zaragoza was named after the city of Zaragoza, Spain, since among the first settlers of the place families were some of the city from Aragon.

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] |
Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of t ...

Wet Season
The wet season (sometimes called the Rainy season) is the time of year when most of a region's average annual rainfall occurs. It is the time of year where the majority of a country's or region's annual precipitation occurs. Generally, the season lasts at least a month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M.

Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Water Stagnation
Water stagnation occurs when water stops flowing. Stagnant water can be a major environmental hazard. Dangers Malaria and dengue are among the main dangers of stagnant water, which can become a breeding ground for the mosquitoes that transmit these diseases. Stagnant water can be dangerous for drinking because it provides a better incubator than running water for many kinds of bacteria and parasites. Stagnant water can be contaminated with human and animal feces, particularly in deserts or other areas of low rainfall. Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. Stagnant water may be classified into the following basic, although overlapping, types: * Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) * Surface and ground waters stagnation * Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...
