Río Pilcomayo National Park
The Río Pilcomayo National Park () is a national park located in the northeastern part of the Argentina, Argentine province of Formosa Province, 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 Ramsar wetlands of international importance, list of wetlands of international importance. Topography The park occupies a large plain, which was formed when a depression in Paleozoic Crystalline#Crystalline rocks, crystalline rocks was filled with organic and inorganic sediments, thus creating a sedimentary basin. The uppermost sediment levels are of fluvial and Aeolian processes, 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 Fault (geology), faults ... [...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 (currently ) meaning "beautiful". The name or 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 Asunción. Because the Pilcomayo and Bermejo Rivers are so shall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). 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. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-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 radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: # "A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; # "A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: # "Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; # "BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, th ...

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 province of Formosa, and less abundantly towards drier areas). They often, but not always, form dense single-species woodlands. Its common names in Spanish show the various colours (and technical qualities) that the trunk takes according to its environment: ''palma blanca'', ''palma negra'', ''palma colorada'' ("white", "black", and "red" palm, respectively). In 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 Carnauba wax palm). Description ''C. alba'' can reach 25 m in height and 40 cm in girth. The trunk is cylindrical, rarely bifurcated, and has a grayish trunk with a smooth surface in adult specimens. The leaves are persistent, grouped at the apex of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and 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. Four savanna forms exist; ''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 forests.Manoel Cláudio da ...

Tornado
A tornado is a violently rotating column of air that is in contact with the surface of 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 Hemisphere. Tornadoes come in many shapes and sizes, and they are often (but not always) visible in the form of a funnel cloud, 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 Tornado records#Highest winds observed in a tornado, most extreme tornadoes can attain wind speeds of mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones immediately to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° to 40° 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 climate, humid subtropical (Köppen climate classification: Cfa/Cwa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification: Csa/Csb), where seasonal rainfall is concentrated in the cooler ...

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 by humans as being in the same celestial sphere, celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. Due to Earth's axial tilt of 23.439281°, there is a seasonal variation in the lengths of the day and night. There is also a seasonal variation in temperatures, which lags the variation in day and night. Conventionally, winter in the Northern Hemisphere is taken as the period from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer is taken as the period 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 weather patterns that aff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, the clade consisting of all other modern birds except the galliformes and paleognaths. 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
