Spain
–
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Valencia, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and later by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians, Basques and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula. The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth

Autonomous communities of Spain
–
Spain is not a federation, but a highly decentralized unitary state. Some scholars have referred to the system as a federal system in all. There are 17 autonomous communities and two cities that are collectively known as autonomies. The two autonomous cities have the right to become autonomous communities, but neither has yet used this right and this unique framework of territorial administration is known as the State of Autonomies. The autonomous communities are governed according to the constitution and their own organic laws known as Statutes of Autonomy, since devolution was intended to be asymmetrical in nature, the scope of competences vary for each community, but all have the same parliamentary structure. Spain is a country made up of different regions with varying economic and social structures, as well as different languages. While the entire Spanish territory was united under one crown by the 16th century, the constituent territories—be it crowns, kingdoms, principalities or dominions—retained much of their former institutional existence, including limited legislative, judicial or fiscal autonomy. These territories also exhibited a variety of customs, laws. From the 18th century onwards, the Bourbon kings and the government tried to establish a more centralized regime, leading figures of the Spanish Enlightenment advocated for the building of a Spanish nation beyond the internal territorial boundaries. This culminated in 1833, when Spain was divided into 49 provinces and these were the Basque Country and Catalonia. This gave rise to peripheral nationalisms along with Spanish nationalism, therefore, economic and social changes that had produced a national cultural unification in France had the opposite effect in Spain. In a response to Catalan demands, limited autonomy was granted to Catalonia in 1913 and it was granted again in 1932 during the Second Spanish Republic, when the Generalitat, Catalonias mediaeval institution of government, was restored. During General Francos dictatorial regime, centralism was most forcefully enforced as a way of preserving the unity of the Spanish nation, peripheral nationalism, along with communism and atheism were regarded by his regime as the main threats. When Franco died in 1975, Spain entered into a phase of transition towards democracy, the then Prime Minister of Spain, Adolfo Suárez, met with Josep Tarradellas, president of the Generalitat of Catalonia in exile. An agreement was made so that the Generalitat would be restored and limited competencies would be transferred while the constitution was still being written. In the end, the constitution, published and ratified in 1979, found a balance in recognizing the existence of nationalities and regions in Spain, within the indissoluble unity of the Spanish nation. The starting point in the organization of Spain was the second article of the constitution. In order to exercise this right, the established a open process whereby the nationalities

Aragon
–
Aragon is an autonomous community in Spain, coextensive with the medieval Kingdom of Aragon. Located in northeastern Spain, the Aragonese autonomous community comprises three provinces, Huesca, Zaragoza, and Teruel, the current Statute of Autonomy declares Aragon a nationality of Spain. Aragons northern province of Huesca borders France and is positioned in the middle of the Pyrenees, within Spain, the community is flanked by Catalonia to the east, Valencia and Castile–La Mancha to the south, and Castile and León, La Rioja, and Navarre to the west. Aragon is home to many rivers—most notably, the river Ebro, Spains largest river in volume and it is also home to the Aneto, the highest mountain in the Pyrenees. As of 2015, the population of Aragon was 1,317,847, with more than half of it living in Zaragoza. As of 2015, half of Aragons population,50. 45%, Huesca is the only other city in the region with a population greater than 50,000. The majority of Aragonese citizens,71. 8%, live in the province of Zaragoza,17. 1% in Huesca and 11. 1% in Teruel, the population density of the region is the second lowest in Spain, only 26, 8/km2, after Castilla La Mancha. Only four cities have more than 20,000 inhabitants, Zaragoza 700,000, Huesca 50,000, Teruel 35,000 and Calatayud 20,000. Spanish is the language in most of Aragon, and it is the only official language, understood. The strip-shaped Catalan-speaking area in Aragon is often called La Franja, with such a low population density large areas of Aragon remain wild and relatively untouched. It is a land of natural contrasts, both in climate and geologically, from the green valleys and snow-capped peaks of the Pyrenees to the dry plains. Aragons Pyrenees include splendid and varied mountain landscapes with soaring peaks, deep canyons, dense forests and its rugged peaks include the Aneto, the highest in the range, the misty Monte Perdido, Perdiguero, Cotiella and many others. The park is one of the last sanctuaries of birds of prey in the range. Many beautiful mountain butterflies and flowers can be seen in the summer, the principal valleys in the mountains include those of Hecho, Canfranc, Tena, Benasque and others. The green valleys hide pretty villages with nice Romanesque churches and typical Pyrenean houses with flowers on the balconies, the oldest Romanesque cathedral in Spain is located in the medieval town of Jaca in the very northern part of Huesca Province. In the Pyrenean foothills, or pre-Pyrenees, the Mallos de Riglos are a natural rock formation. Ancient castles nestle on lonely hills, the most famous being the magnificent Loarre Castle, further south, the Ebro valley, irrigated by the river Ebro, is a rich and fertile agricultural area covered with vast fields of wheat, barley and other fruit and vegetable crops. Many beautiful and little-known settlements, castles and Roman ruins dot the landscape here, some of the most notable towns here include Calatayud, Daroca, Sos del Rey Catolico, Caspe and others

Mining
–
Mining is extraction of valuable minerals or other geological materials from the earth usually from an orebody, lode, vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner, ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times, Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines, levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products, due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves. Since the beginning of civilization, people have used stone, ceramics and, later and these were used to make early tools and weapons, for example, high quality flint found in northern France, southern England and Poland was used to create flint tools. Flint mines have been found in areas where seams of the stone were followed underground by shafts. The mines at Grimes Graves and Krzemionki are especially famous, other hard rocks mined or collected for axes included the greenstone of the Langdale axe industry based in the English Lake District. The oldest-known mine on archaeological record is the Lion Cave in Swaziland, at this site Paleolithic humans mined hematite to make the red pigment ochre. Mines of an age in Hungary are believed to be sites where Neanderthals may have mined flint for weapons. Ancient Egyptians mined malachite at Maadi, at first, Egyptians used the bright green malachite stones for ornamentations and pottery. Later, between 2613 and 2494 BC, large building projects required expeditions abroad to the area of Wadi Maghareh in order to secure minerals and other resources not available in Egypt itself. Quarries for turquoise and copper were found at Wadi Hammamat, Tura, Aswan and various other Nubian sites on the Sinai Peninsula. Mining in Egypt occurred in the earliest dynasties, the gold mines of Nubia were among the largest and most extensive of any in Ancient Egypt. These mines are described by the Greek author Diodorus Siculus, who mentions fire-setting as one used to break down the hard rock holding the gold. One of the complexes is shown in one of the earliest known maps, the miners crushed the ore and ground it to a fine powder before washing the powder for the gold dust

Open-pit mining
–
Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, for minerals that occur deep below the surface—where the overburden is thick or the mineral occurs as veins in hard rock—underground mining methods are used to extract the valued material. Open-pit mines that produce building materials and dimension stone are commonly referred to as quarries, open-pit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic. When this occurs, the mines are sometimes converted to landfills for disposal of solid wastes. Open-cast mines are dug on benches, which describe vertical levels of the hole and these benches are usually on four to sixty meter intervals, depending on the size of the machinery that is being used. Many quarries do not use benches, as they are usually shallow, most walls of the pit are generally blast mined on an angle less than vertical, to prevent and minimize damage and danger from rock falls. This depends on how weathered the rocks are, and the type of rock, the inclined section of the wall is known as the batter, and the flat part of the step is known as the bench or berm. The steps in the walls help prevent rock falls continuing down the face of the wall. In some instances additional ground support is required and rock bolts, cable bolts, de-watering bores may be used to relieve water pressure by drilling horizontally into the wall, which is often enough to cause failures in the wall by itself. A haul road is situated at the side of the pit, forming a ramp up which trucks can drive, carrying ore. Waste rock is piled up at the surface, near the edge of the open pit and this is known as the waste dump. The waste dump is also tiered and stepped, to minimize degradation, ore which has been processed is known as tailings, and is generally a slurry. This is pumped to a dam or settling pond, where the water evaporates. This toxicity can harm the surrounding environment, after mining finishes, the mine area may undergo land rehabilitation. Waste dumps are contoured to flatten out, to further stabilise them. This is then covered with soil, and vegetation is planted to help consolidate the material. There are no long term studies on the success of these due to the relatively short time in which large scale open pit mining has existed. It may take hundreds to thousands of years for some waste dumps to become acid neutral, the dumps are usually fenced off to prevent livestock denuding them of vegetation

Mountain
–
A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism and these forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, a few mountains are isolated summits, but most occur in huge mountain ranges. High elevations on mountains produce colder climates than at sea level and these colder climates strongly affect the ecosystems of mountains, different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m, there is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain, whether a landform is called a mountain may depend on local usage. The highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m, similarly, Mount Scott outside Lawton, Oklahoma is only 251 m from its base to its highest point. Whittows Dictionary of Physical Geography states Some authorities regard eminences above 600 metres as mountains, in addition, some definitions also include a topographical prominence requirement, typically 100 or 500 feet. For a while, the US defined a mountain as being 1,000 feet or taller, any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US, using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As a whole, 24% of the Earths land mass is mountainous, there are three main types of mountains, volcanic, fold, and block. All three types are formed from plate tectonics, when portions of the Earths crust move, crumple, compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of the feature makes it either a hill or, if higher and steeper, major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate, at a depth of around 100 km, melting occurs in rock above the slab, and forms magma that reaches the surface. When the magma reaches the surface, it builds a volcanic mountain. Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines, the magma does not have to reach the surface in order to create a mountain, magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US
