Sierra De La Culebra
The Sierra de la Culebra, or Serra da Coroa (in Portuguese), is a mountain range in Castile and León, northwest Spain, and northeastern Portugal. It lies 7 km south of Puebla de Sanabria in the comarcas of Aliste, Sanabria and La Carballeda ( Zamora Province), as well as Vinhais and Bragança municipalities in the District of Bragança. Its highest point is high Peña Mira, located near Flechas, within Figueruela de Arriba municipal term; other important peaks are Miño Cuevo and La Pedrizona . The Sierra de la Culebra is a 95 km long regular mountain chain of medium height, forming a natural border with the Portuguese region of Tras os Montes on its western end. Its slopes are wooded, occasionally ravaged by forest fires. The summits of the range are often covered with snow in the winter and there are odd-looking rocky quartzite outcrops on them. Among the rivers in Spain and Portugal having their source in Sierra de la Culebra, the Castro River, Tera, Tuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

Flechas
The Flechas (Portuguese for ''Arrows'') were a elite paramilitary tactical unit of the Portuguese secret police (PIDE, latter renamed DGS) that operated in Angola and Mozambique during the Portuguese Colonial War. Unlike most of the other Portuguese special forces that were employed in the several theatres of operations of the conflict, the Flechas were not a ''de jure'' military unit but a PIDE/DGS (secret police) unit. Flechas were organized as platoon-sized units consisting of local tribesmen and rebel defectors who specialised in black operation, clandestine operation, close-quarters combat, counterinsurgency, covert operation, desert warfare, direct action, irregular warfare, pseudo-operations, jungle warfare, raiding and kidnapping high-value target, special operations, special reconnaissance, tracking, and urban warfare. They sometimes patrolled in captured uniforms and were rewarded with cash bounties for every guerrilla or guerrilla weapon they captured. Flechas had a re ...

Macizo Galaico-Leonés
The Galician Massif ( es, Macizo Galaico, also known as ''Macizo Galaico-Leonés'') is a system of mountain ranges in the northwestern corner of the Iberian Peninsula. It is located in Galicia with its southeastern end reaching into the provinces of Zamora and León of Castile and León. Its highest point is Pena Trevinca at . Another important peak is Cabeza de Manzaneda (1,781 m). In traditional local folklore the forests of the Galician System are said to be inhabited by a variety of elves, fairies, ghosts, the Santa Compaña, the Nubeiro and witches ''(meigas)''. Geology Geomorphologically the Galician Massif is a northwestern prolongation of the Meseta Central, the inner Iberian plateau and has great affinity with the geology of the Tras os Montes Portuguese region, so that it is considered as a whole under the name 'Galicia-Trás-os-Montes Zone'. It is composed of Paleozoic materials (granite) with metamorphic rocks such as gneiss, slate and schist in the center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sabor River
Sabor River, ''Rio Sabor'' in Portuguese, is a river that rises in Spain and enters Portugal in the Natural Park of Montesinho, in the northeast of the country. It is a tributary of the right bank of the Douro River, passing near the city of Bragança from where it receives the waterbody of the River Fervença, going to empty close to the Torre de Moncorvo downstream of the Pocinho Dam, in the village of Foz do Sabor. The Sabor River basin is a large basin (3170 km2) located in the northeast of Portugal and used mostly for agroforestry Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland. Trees produce a wide range of useful and marketable products from fruits/nuts, medicines, wood products, etc. This intentional ....Hydrologic and Water Allocation Model to Assess Water Availability in the Sabor River Basin (Portugal), July 2019 International Journal of Environmental Research and Public Health 16(13):2419, DOI: 1 ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
