Gruta Das Cinco Ribeiras
The Gruta das Cinco Ribeiras (literally the ''Cave of Cinco Ribeiras'') is a cave situated in the southwest coast of Terceira, located in the civil parish of Cinco Ribeiras, municipality of Angra do Heroísmo, in the Portuguese archipelago of the Azores. The cave is situated along the coast near the Porto das Cinco Ribeiras and the surrounding bay, primarily accessible by boat from along the coast. The geological formation is directly related with the former-volcano of Serra de Santa Bárbara Serra de Santa Bárbara is the peak of an inactive volcano in the western part of the island of Terceira, Azores, Portugal. At elevation, it is the highest point of the island. It is named after the village located on the coast to the south, Sa ..., and is characterized by high areals, lava flows and pyroclasts that created perfect stratifications of geological materials. It is associated specifically with a lava tube and arches created during the eruptions of the Santa Bárbara volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terceira Island
Terceira () is a volcanic island in the Azores archipelago, in the middle of the North Atlantic Ocean. It is one of the larger islands of the archipelago, with a population of 53,311 inhabitants in an area of approximately . It is the location of the Azores' oldest city, Angra do Heroísmo, the historical capital of the archipelago and UNESCO World Heritage Site; the seat of the judicial system (Supreme Court); and the main Air Force base, Lajes Field, Base Aérea nº 4 at Lajes, with a United States Air Force detachment. The island has two main sea ports, one at Angra do Heroísmo and the other at Praia da Vitória, and a commercial airport integrated with the flight operations at Lajes Field, Base Aérea nº 4. The Portuguese bullfight is popular on the island, coming in two variations: the traditional equestrian bullfight (in the ring) and the popular "touradas à corda" that occur in the streets.

Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Freguesia (Portugal)
''Freguesia'' (), usually translated as "parish" or "civil parish", is the third-level administrative subdivision of Portugal, as defined by the 1976 Constitution. It is also the designation for local government jurisdictions in the former Portuguese overseas territories of Cape Verde and Macau (until 2001). In the past, was also an administrative division of the other Portuguese overseas territories. The ''parroquia'' in the Spanish autonomous communities of Galicia and Asturias is similar to a ''freguesia''. A ''freguesia'' is a subdivision of a ''município'' (municipality). Most often, a parish takes the name of its seat, which is usually the most important (or the single) human agglomeration within its area, which can be a neighbourhood or city district, a group of hamlets, a village, a town or an entire city. In cases where the seat is itself divided into more than one parish, each one takes the name of a landmark within its area or of the patron saint from the usually cot ...

Concelho
Concelho () is the Portuguese-language term for municipality, referring to the territorial subdivision in local government. In comparison, the word ''município'' () refers to the organs of State. This differentiation is still in use in Portugal and some of its former overseas provinces, but is no longer in use in Brazil following the abolition of these organs, in favour of the French prefecture system. It is similar to borough and council. History After the civil parish ( pt, freguesias), the Portuguese ''concelho'' is the most stable territorial subdivision within the country, with over 900 years of history. Founded in the royal charters attributed to parcels and territorial enclaves, in order to establish a presence by the Crown, rather than personal fiefdoms of the nobility and aristocracy. This municipal institution changed throughout history: many were abolished and reconstituted based on the political necessity; first they were subject to the specifics of each charter (wh ...

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 ...
