Mount Merapi
Mount Merapi (, ) is an active stratovolcano located on the border between the province of Central Java and the Special Region of Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately north of Yogyakarta city which has a population of 2.4 million. Thousands of people live on the flanks of the volcano, with villages as high as above sea level. Smoke can often be seen rising from the mountaintop, and several eruptions have caused fatalities. A pyroclastic flow from a large explosion killed 27 people on 22 November 1994, mostly in the town of Muntilan, west of the volcano. Another large eruption occurred in 2006, shortly before the Yogyakarta earthquake. In light of the hazards that Merapi poses to populated areas, it was designated as one of the Decade Volcanoes, which are considered worthy of particular study in light of their history of large, destructive eruptions and proximity to densely popul ...

BBC Bitesize
BBC Bitesize, also abbreviated to ''Bitesize'', is the BBC's free online study support resource for school-age people in the United Kingdom. It is designed to aid people in both schoolwork and, for older people, exams. History ''GCSE Bitesize'' was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home. In 2023, videos from ''Bitesize'' were adapted and dubbed over in Dari and Pashto in order to be broadcast in Afghanistan, where education for girls has been stopped by the Taliban government. The show was called '' Dars'', which means "lessons" in both languages. National sections England The Key Stage 1, 2 and 3 along with GCSE section covers a range of subjects. In Key Stage 1, 17 subjects are available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Geology of Mars, Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) to porphyritic (coarse-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspa ... [...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 ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also 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. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunda Plate
The Sunda plate is a minor tectonic plate straddling the equator in the Eastern Hemisphere on which the majority of Southeast Asia is located. The Sunda plate was formerly considered a part of the Eurasian plate, but the GPS measurements have confirmed its independent movement at 10 mm/yr eastward relative to Eurasia. Extent The Sunda plate includes the South China Sea, the Andaman Sea, southern parts of Vietnam, Myanmar, Laos and Thailand along with Malaysia, Singapore, Cambodia, southern Philippines, and the islands of Bali, Lombok, West Nusa Tenggara, Borneo, Sumatra, Java, and part of Sulawesi in Indonesia. The Sunda is bounded in the east by the Philippine Mobile Belt, Molucca Sea Collision Zone, Molucca Sea plate, Banda Sea plate and Timor plate; to the south and west by the Australian plate; and to the north by the Burma plate, Eurasian plate; and Yangtze plate. The Indo-Australian plate dips beneath the Sunda plate along the Sunda Trench also known as Jav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subduction
Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at the convergent boundaries between tectonic plates. Where one tectonic plate converges with a second plate, the heavier plate dives beneath the other and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with rates of convergence as high as 11 cm/year. Subduction is possible because the cold and rigid oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle. Once initiated, stable subduction is driven mostly by the negative buoyancy of the dense subducting lithosphere. The down-going slab sinks into the mantle largely under its own ...

Mount Meru (mythology)
Mount Meru (Sanskrit/Pali: मेरु)—also known as Sumeru, Sineru or Mahāmeru—is a sacred, five-peaked mountain present within Hindu, Jain and Buddhist cosmologies, revered as the centre of all physical, metaphysical and spiritual universes. It is professed to be located at the junction of the four great cosmic continents—Pubbavideha Dīpa, Uttarakuru Dīpa, Amaragoyāna Dīpa and Jambu Dīpa. Despite not having a clearly identified or known geophysical location, Mount Meru is, nevertheless, always thought of as being either in the Himalayan Mountains or the Aravalli Range (in western India). Mount Meru is also mentioned in scriptures of other, external religions to India, such as Taoism—which was influenced, itself, by the arrival of Buddhism in China. Many Hindu, Jain and Buddhist temples have been built as symbolic representations of Mount Meru. The "Sumeru Throne" ( :zh:须弥座; ''xūmízuò'') style is a common feature of Chinese pagodas.

Sanskrit
Sanskrit (; stem form ; nominal singular , ,) is a classical language belonging to the Indo-Aryan languages, Indo-Aryan branch of the Indo-European languages. It arose in northwest South Asia after its predecessor languages had Trans-cultural diffusion, diffused there from the northwest in the late Bronze Age#South Asia, Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a lingua franca, link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting effect on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Indo-Aryan languages# ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
