Cordillera Central (Costa Rica)
The Cordillera Central is a volcanic mountain range in central Costa Rica which continues from the Continental Divide to east of Cordillera de Tilarán. It extends 80 km from Tapezco Pass to the Turrialba Volcano and ends on the Pacuare River. It is separated from Cordillera de Tilarán by Balsa River and Platanar and Zarcero hills. The Cordillera Central is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica. It contains four large volcanoes Poás (2,708 m), Barva (2,906 m), Irazú and Turrialba (3,340 m). The highest peak is Irazú at 3,432 m. South of the range lie elevated plains of central tectonic depression of Costa Rican Central Valley. Cordillera Central's four main volcanoes are protected as national parks A national park is a nature park designated for conservation (e ...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. Some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high to intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but can travel as far as 8 km (5 mi). The term ''composite volcano'' is used because strata are usually mixed and uneven instead of neat layers. They are among the most common types of volcanoes; more than 700 stratovolcanoes have erupted lava during the Holocene Epoch (the last 11,700 years), and many ol ...

Inactive Volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...

Poás Volcano
The Poás Volcano (), is an active stratovolcano in central Costa Rica and is located within Poas Volcano National Park. It has erupted 40 times since 1828, with a strong eruption on April 2017—causing the evacuation of visitors and residents. The volcano and surrounding park were closed for nearly 17 months, with a 2.5 kilometer safety perimeter established around the erupting crater. On September 1, 2018, the park was reopened to the public only with limited access to the crater observation area. They have started to require a reservation on the National Park Website before visitation. Adjacent trails to Lake Botos, and the museum at the visitor center remained closed. The volcano erupted briefly twice in September 2019. Crater lakes There are two crater lakes near the summit. The northern lake is known as the ''Laguna Caliente'' ("hot lagoon") and is located at a height of 2,300 m in a crater approximately 0.3 km wide and 30 m deep. It is one of the world' ...

Poás Volcano National Park
Poás Volcano National Park () is a national park in Costa Rica that covers an area of approximately ; the summit of Poás Volcano located within the park is at an elevation of . The park was established on 25 January 1971. Depending on conditions, visitors can walk all the way to the edge of the main crater, but on 13 April 2017 the park was closed to visitors due to an explosive eruption on the evening of 12 April. Still further eruptions, including on Easter, 16 April, caused the park to be closed until August 2018. Over the years, the park has been frequently closed to visitors due to precautions because of water vapor and sulfuric acid gas emissions. The status of the park being subject to change, potential visitors should check the current conditions at the park. Poas Volcano erupted twice briefly in September 2019. The volcano is located in the Central Conservation Area located in the Alajuela Province near the Pacific coast of Costa Rica, which encompasses the area aroun ...

Platanar Volcano
Platanar Volcano is located in the Cordillera Central mountain range. It is part of a complex that covers and is dominated by Porvenir Volcano at . It is located within the Juan Castro Blanco National Park. Physical aspects It has a destroyed crater to the northwest. Prehistoric lava flows on its western flank; one of them, the so-called Florida flow, was perhaps created by Platanar's most recent activity. Cerro Porvenir has a truncated caldera at the summit with a cone inside. Both of these are part of a composed stratovolcano of Upper Pleistocene age that on Platanar's side overlies the remains of Palmera's collapsed caldera, of probable late Pleistocene age. Platanar has erupted lavas ranging from basalts to andesites in composition. Social and economic activities The western flanks of both volcanoes are used for dairy farm Dairy farming is a class of agriculture for the long-term production of milk, which is processed (either on the farm or at a dairy plant, e ...

Sitting Alouatta Palliata, Costa Rica
Sitting is a basic action and resting position in which the body weight is supported primarily by the bony ischial tuberosities with the buttocks in contact with the ground or a horizontal surface such as a chair seat, instead of by the lower limbs as in standing, squatting or kneeling. When sitting, the torso is more or less upright, although sometimes it can lean against other objects for a more relaxed posture. Sitting for much of the day may pose significant health risks, with one study suggesting people who sit regularly for prolonged periods may have higher mortality rates than those who do not. The average person sits down for 4.7 hours per day, according to a global review representing 47% of the global adult population. The form of kneeling where the buttocks sit back on the heels, for example as in the ''Seiza'' and ''Vajrasana'' postures, is also often interpreted as sitting. Prevalence The British Chiropractic Association said in 2006 that 32% of the British pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mantled Howler
The mantled howler (''Alouatta palliata'') is a species of howler monkey, a type of New World monkey, from Central America, Central and South America. It is one of the monkey species most often seen and heard in the wild in Central America. It takes its "mantled" name from the long guard hairs on its sides. The mantled howler is one of the largest Central American monkeys, and males can weigh up to . It is the only Central American monkey that eats large quantities of leaves; it has several adaptations to this folivorous diet. Since leaves are difficult to digest and provide less energy than most foods, the mantled howler spends the majority of each day resting and sleeping. The male mantled howler has an enlarged hyoid bone, a hollow bone near the vocal cords, which amplifies the calls made by the male, and is the reason for the name "howler". Howling allows the monkeys to locate each other without expending energy on moving or risking physical confrontation. The mantled howler ...
