Cabo De Gata-Níjar Natural Park
''Cabo de Gata-Níjar'' Natural Park in the southeastern corner of Spain is Andalusia's largest protected coastal area, a wild and isolated landscape. Spain's southeast coast, where the park is situated, is a region in mainland Europe with a hot desert climate (Köppen climate classification: BWh). The eponymous mountain range of the ''Sierra del Cabo de Gata'', with its highest peak El Fraile, form a volcanic rock formation with sharp peaks and crags in red and ochre hues. It falls steeply to the Mediterranean Sea, creating jagged high cliffs riven by gullies, creating hidden coves and white, sandy beaches. Offshore are numerous tiny rocky islands and extensive coral reefs teeming with marine life. Its climate is dry, with rainfall below a year and average yearly temperatures above . In 1997, it was designated as a UNESCO Biosphere Reserve. In 2001, it was included among the Specially Protected Areas of Mediterranean Importance, due to the adsorptive properties and low per ...

Almería (province)
Almería (, , ) is a city and municipalities in Spain, municipality of Spain, located in Andalusia. It is the capital of the province of Almería, province of the same name. It lies on southeastern Iberian Peninsula, Iberia on the Mediterranean Sea. Caliph Abd al-Rahman III founded the city in 955. The city grew wealthy during the Islamic era, becoming a world city throughout the 11th and 12th centuries. It enjoyed an active port that traded Almerían silk, silk, oil and raisins. Etymology The name "Almería" comes from the city's former Arabic name, ''Madīnat al-Mariyya'', meaning "city of the watchtower". As the settlement was originally port or coastal suburb of Pechina, it was initially known as ''Mariyyat al-Bajjāna'' (''Bajjāna'' being the Arabic name for Pechina). History The origin of Almería is connected to the 9th-century establishment of the so-called Republic of Pechina (Bajjana) some kilometres to the north, which was for a time autonomous from the Emirate of ...

Posidonia
''Posidonia'' is a genus of flowering plants. It contains nine species of marine plants ("seagrass"), found in the seas of the Mediterranean and around the south coast of Australia. The APG system (1998) and APG II system (2003) accept this genus as constituting the sole genus in the family Posidoniaceae, which it places in the order Alismatales, in the clade monocots. The AP-Website concludes that the three families Cymodoceaceae, Posidoniaceae and Ruppiaceae form a monophyletic group. Earlier systems classified this genus in the family Potamogetonaceae or in the family Posidoniaceae but belonging to order Zosterales. ''Posidonia oceanica'' has nitrogen fixation capabilities via symbiosis and other species may as well. Species This is a list of species that are contained by the genus: *''Posidonia angustifolia'' Cambridge and Kuo *''Posidonia australis'' Hook.f. South coast of Australia. *''Posidonia coriacea'' Cambridge and Kuo *''Posidonia denhartogii'' Kuo and Cambridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

European Geoparks Network
The European Geoparks Network (EGN) functions as the regional organization of the Global Geoparks Network (GGN) and the UNESCO International Geosciences and Geoparks Programme (UNESCO-IGGP). Its main objective is to ensure cooperation between geoparks for the protection of geological heritage and the promotion of sustainable development of their territories in Europe. In 2020 January, the EGN had 75 institutional members (UNESCO Global Geoparks) from 26 European countries and there are several aspiring geopark projects, applying for a UNESCO label and therefore the permanent EGN membership. History The 1990s are widely considered as the birth of geoheritage as a dedicated domain of the geosciences, dealing with the preservation and valorisation of the Earth's abiotical heritage, its geodiversity. The idea of coordinated work on geology-focused territorial frameworks in Europe was discussed during the International Geological Congress in Beijing, 1997. After preparatory meetings ...

Global Geoparks Network
UNESCO Global Geoparks (UGGp) are geoparks certified by the UNESCO Global Geoparks Council as meeting all the requirements for belonging to the Global Geoparks Network (GGN). The GGN is both a network of geoparks and the agency of the United Nations Educational, Scientific and Cultural Organization (UNESCO). that administers the network. The agency was founded in 2004 in partnership with the International Union of Geological Sciences (IUGS). The network was set up to conserve earth's geological heritage, as well as to promote the sustainable research and development by the concerned communities. To implement these goals they adopted the concept of geopark, a term that had already been in use for one of the proposed parks. Geoparks were conceived as :"single, unified geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development." As the geopark did not naturally conform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Flows
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces.
