Algar Do Carvão
The Algar do Carvão (''Cavern of Coal'') is an ancient lava tube or volcanic vent located in the central part of the island of Terceira Island, Terceira in the Portugal, Portuguese archipelago of the Azores. It lies within the Freguesia (Portugal), civil parish of Porto Judeu in the Concelho, municipality of Angra do Heroísmo. History The existence of the cavern had been known for a long time, but the depth and lack of ambient light, made any descent difficult, owing to the vertical descent, and delayed any real exploration.Paulo Barcelos/SIARAM (September 2010) On 26 January 1893, the first descent, ''"...with the use of a simple rope, was accomplished by Cândido Corvelo and Luis Sequeira."'' The second descent was made in 1934, by Didier Couto, who produced the first rough map of the interior. This drawing, based on visual observations alone (rather than measurements), turned out to be quite accurate. On 18 August 1963, a group of enthusiasts organized a descent using a "c ...

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 Tubes
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] |
Caves Of The Azores
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms ...

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Springtail
Springtails (Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects (the other two are the Protura and Diplura). Although the three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts. Collembolans are omnivorous, free-living organisms that prefer moist conditions. They do not directly engage in the decomposition of organic matter, but contribute to it indirectly through the fragmentation of organic matter and the control of soil microbial communities. The word ''Collembola'' is from the ancient Greek "glue" and "peg"; this name was given due to the existence of the collophore, which was previously thought to stick to surfaces to stabilize the creature. Some DNA sequence studies suggest that Collembola represent a separate evolutionary line fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithobius Obscurus Azorae
''Lithobius'' is a large genus of centipedes in the family Lithobiidae, commonly called stone centipedes, common centipedes or brown centipedes. Anatomy Most ''Lithobius'' species are typical representatives of the family Lithobiidae. They are about long and brownish in colour. The adult's body has 18 segments, and 15 pairs of legs. The special characteristics include the dispersed openings of coxal glands of the last pair of legs. Ecology Stone centipedes are found under stones or bark, in soil and decaying matter. Some are common in gardens. ''Lithobius forficatus'' is the most abundant centipede species in Europe. Like other centipedes, they are more active at night. They feed on insects and other small invertebrates. The eggs are deposited singly in soil. The lifespan can be over 3 years. Taxonomy The genus ''Lithobius'' was erected in 1814 by William Elford Leach, in an article published in David Brewster's ''Edinburgh Encyclopædia''. The name derives from two Greek roo ...
