Río Pilcomayo National Park
The Río Pilcomayo National Park ( es, Parque Nacional Río Pilcomayo) is a national park located in the northeastern part of the Argentine province of Formosa, on the border with Paraguay. Established on September 29, 1951 to protect the natural features (grasslands, marshes, creeks, lakes and forests), typical of the Humid Chaco ecoregion, the park is included in the Ramsar Convention's list of wetlands of international importance. Topography The park occupies a large plain, which was formed when a depression in Paleozoic crystalline rocks was filled with organic and inorganic sediments, thus creating a sedimentary basin. The uppermost sediment levels are of fluvial and aeolian origin. The eastern parts of the park are dominated by silts and clays, creating less permeable soils, while the western parts contain soils that are coarser and more porous. There are faults that were generated during formation of the Andes, lying parallel to the Paraguay River. While the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formosa Province
Formosa Province () is a province in northeastern Argentina, part of the Gran Chaco Region. Formosa's northeast end touches Asunción, Paraguay, and the province borders the provinces of Chaco and Salta to its south and west, respectively. The capital is Formosa. Source of the provincial name The name of the city (and the province) comes from the archaic Spanish word ''fermosa'' (currently ''hermosa'') meaning "beautiful". The name ''Vuelta Fermosa'' or ''Vuelta la Formosa'' was used by Spanish sailors in the 16th century to describe the area where the Paraguay River makes a turn, right in front of the actual city. These sailors were searching for the legendary Sierra del Plata. History Native inhabitants of these lands include the Pilagás, Wichis and Tobas, whose languages are still spoken in the province. Sebastian Cabot and Diego García de Moguer first explored the area at the beginning of the 16th century trying to find a route from Viceroyalty of Peru to ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caranday Wax Palm
''Copernicia alba'' is a South American species of palm tree, which is found in the Humid Chaco ecoregion in Bolivia, Paraguay, Colombia, Brazil (in the states of Mato Grosso and Mato Grosso do Sul) and Argentina (especially the provinces of Argentina, province of Formosa Province, Formosa, and less abundantly towards drier areas). They often, but not always, form dense single-species woodlands. Its common names in Spanish language, Spanish show the various colours (and technical qualities) that its wood and/or Bark (botany), bark takes according to its environment: ''palma blanca'', ''palma negra'', ''palma colorada'' ("white", "black", and "red" palm, respectively). In Guaraní language, Guaraní, it is called ''caranday'', "water palm". Its English trade name is wax palm or caranday wax palm (it belongs to the same genus as the Copernicia prunifera, Carnauba wax palm). Ancient peoples in South America used wax palm for making candles by scraping away wax on the leaves. ''C. a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Tornado
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100 ...

Subtropical
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical (Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands.

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter Winter is the coldest season of the year in Polar regions of Earth, polar and temperate climates. It occurs after autumn and before spring (season), spring. The tilt of Axial tilt#Earth, Earth's axis causes seasons; winter occurs when a Hemi ... in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the Year#Astronomical years, astronomical year. Within the Northern Hemisphere, oceanic currents can change the ...

Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bir ...

Pilcomayo River
Pilcomayo (in Hispanicized spelling) (Quechua Pillkumayu or Pillku Mayu, ''pillku'' red, ''mayu'' river, "red river", Guarani Ysyry Araguay ) is a river in central South America. At long, it is the longest western tributary of the Paraguay River. Its drainage basin is in area, and its mean discharge is . Along its course, the Pilcomayo silts up and splits into two main branches, North and South. After some distance, these branches rejoin to form the Lower Pilcomayo. The Pilcomayo rises in the foothills of the Andes mountain range in the Oruro Department in Bolivia, east of Lake Poopó. The Jach'a Juqhu River is considered the origin of the Pilcomayo. Upstream the Jach'a Juqhu River successively receives the names Aguas Calientes and Kachi Mayu. From the confluence with the Chillawa ''(Chillahua)'', the river is called Pilcomayo.

Paraguay River
The Paraguay River (Río Paraguay in Spanish, Rio Paraguai in Portuguese, Ysyry Paraguái in Guarani) is a major river in south-central South America, running through Brazil, Bolivia, Paraguay and Argentina. It flows about from its headwaters in the Brazilian state of Mato Grosso to its confluence with the Paraná River north of Corrientes and Resistencia. Course The Paraguay's source is south of Diamantino in the Mato Grosso state of Brazil. It follows a generally southwesterly course, passing through the Brazilian city of Cáceres. It then turns in a generally southward direction, flowing through the Pantanal wetlands, the city of Corumbá, then running close to the Brazil-Bolivia border for a short distance in the Brazilian states of Mato Grosso and Mato Grosso do Sul. From the city of Puerto Bahia Negra, Paraguay, the river forms the border between Paraguay and Brazil, flowing almost due south before the confluence with the Apa River. The Paraguay makes a long, gent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
