Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus. Before being deposited, the geological detritus was formed by weathering and erosion from the source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers, which are called agents of denudation. Biological detritus was formed by bodies and parts of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies. Sedimentation may also occur as dissolved minerals precipitate from water solution.
Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms. Weathering occurs in situ, that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.
Mount Tambora, or Tomboro, is an active stratovolcano in the northern part of Sumbawa, one of the Lesser Sunda Islands of Indonesia. Tambora is known for its major eruption in 1815. It was formed due to the active subduction zones beneath it, and before the eruption of 1815, it was more than 4,300 metres high, making it then one of the tallest peaks in the Indonesian archipelago.
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks, metamorphic rocks and sedimentary rocks. Rocks form the Earth's outer solid layer, the crust.
The music of Indonesia demonstrates its cultural diversity, the local musical creativity, as well as subsequent foreign musical influences that shaped contemporary music scenes of Indonesia. Nearly thousands of Indonesian islands having its own cultural and artistic history and character. This results in hundreds of different forms of music, which often accompanies by dance and theatre.
Petrology is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because they both contain heavy use of chemistry, chemical methods, and phase diagrams. Sedimentary petrology is, on the other hand, commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock.
Sundaland heath forest, also known as Kerangas forest, is a type of tropical moist forest found on the island of Borneo, which is divided between Brunei, Indonesia, and Malaysia, as well as on the Indonesian islands of Belitung and Bangka, which lie to the west of Borneo.
Kisar, also known as Yotowawa, is a small island in the Southwestern Moluccas in Indonesia. It is included within the Southernmost Islands District within the Southwest Islands Regency of the Maluku Province; the District also includes the larger Romang Island further north. It is one of the 92 officially listed outlying islands of Indonesia. The principal town is Wonreli, with 6,652 inhabitants at the 2010 Census.
Rock Indo is rock music from Indonesia, a product of the culture and globalizing outlook of the country, similar to this genre's music globally. Indonesian-specific ideas about individualism, interdependency, modernism, and the supernatural have also been observed in the rock videos and music of the nation. Some Indonesian rock bands sometimes perform in the Dangdut style, which was created as a reaction to the influx of popular American music into the country in the 1960s. Due to the politicizing of the Dangdut form in the 1980s, forms of rock which contained more foreign influences came to represent dissent from the Suharto government.
Granite Mountain is a 7,628-foot (2,325 m) mountain located in Yavapai County, Arizona that covers roughly 12 square miles (31 km2). It was once known as Mount Gurley, for the first governor of the Arizona Territory, John A. Gurley. Its southwest face has a sheer granite cliff approximately 500 feet high that is one of the best locations for rock climbing in the state of Arizona. It is located in the Granite Mountain Wilderness, which is managed as a part of the Prescott National Forest. The mountain stands at the northern end of the Sierra Prietas, and borders Skull Valley on the west, on the northwest by the Santa Maria Mountains, and east by the Williamson Valley.
Located in the western Pacific Ocean near Indonesia, the Molucca Sea Plate has been classified by scientists as a fully subducted microplate that is part of the Molucca Sea Collision Complex. The Molucca Sea Plate represents the only known example of divergent double subduction (DDS), which describes the subduction on both sides of a single oceanic plate.
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes the Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field work is an important component of geology, although many subdisciplines incorporate laboratory work.
Shoshonite is a type of igneous rock. More specifically, it is a potassium-rich variety of basaltic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. Shoshonite gives its name to the shoshonite series and grades into absarokite with the loss of plagioclase phenocrysts and into banakite with an increase in sanidine. Shoshonite was named by Iddings in 1895 for the Shoshone River in Wyoming.
Road to Abbey is the first EP by Indonesian rock band J-Rocks released in 2009. It was recorded at the famous Abbey Road Studios in the United Kingdom. This album marked J-Rocks as the first Indonesian band ever to record there.
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust.
Spirit is the second studio album by Indonesian rock band J-Rocks, released on 2007 in Indonesia by Aquarius Musikindo.
Indo-pop also known as Indonesian pop is loosely defined as Indonesian pop music; however, in a wider sense it can also encompass Indonesian pop culture, which also includes Indonesian cinema and sinetrons.
