Molten rock can refer to:
Volcanism, vulcanism or volcanicity is the phenomenon of eruption of molten rock (magma) onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics, and volcanic gases erupt through a break in the surface called a vent. It includes all phenomena resulting from and causing magma within the crust or mantle of the body, to rise through the crust and form volcanic rocks on the surface. Magmas, that reach the surface and solidify, form extrusive landforms.
Geirröðr is a jötunn in Norse mythology. He is the father of the gýgjar Gjálp and Greip, who are killed by the thunder-god Thor.
A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat.
Lapilli is a size classification of tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. Lapilli is Latin for "little stones".
Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron(III) oxide. Iron(II) oxide also refers to a family of related non-stoichiometric compounds, which are typically iron deficient with compositions ranging from Fe0.84O to Fe0.95O.
Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock that was ejected from a volcano as a molten blob and cooled in the air to form discrete grains or clasts. It is typically dark in color, and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water.
Scum or S.C.U.M. may refer to:
Zebra is one of several species of the horse genus Equus whose members have distinctive stripes.
Gilbert Hill is a 200 ft (61 m) monolith column of black basalt rock at Andheri, in Mumbai, India. The rock has a sheer vertical face and was formed when molten lava was squeezed out of the Earth's clefts during the Mesozoic Era about 66 million years ago. During that era, molten lava had spread around most of the Indian states of Maharashtra, Gujarat and Madhya Pradesh, covering an area of 50,000 square kilometres (19,000 sq mi). The volcanic eruptions were also responsible for the destruction of plant and animal life during that era. According to experts, this rare geological phenomenon was the remnant of a ridge and had clusters of vertical columns in nearby Jogeshwari which were quarried off two decades ago. These vertical columns are similar to the Devils Tower National Monument in Wyoming, and the Devils Postpile National Monument in eastern California, USA. Gilbert Hill was declared a National Park in 1952 by the Central Government under the Forest Act. In 2007, after years of lobbying by geologists, the hill was declared a Grade II heritage structure by the Municipal Corporation of Greater Mumbai (MCGM), and all quarrying and other activities around the monument were prohibited. Over the period of time, Gilbert Hill has faced severe erosion problems too.
A molten salt reactor (MSR) is a class of nuclear fission reactor in which the primary nuclear reactor coolant and/or the fuel is a molten salt mixture. Only two MSRs have ever operated, both research reactors in the United States. The 1950's Aircraft Reactor Experiment was primarily motivated by the compact size that the technique offers, while the 1960's Molten-Salt Reactor Experiment aimed to prove the concept of a nuclear power plant which implements a thorium fuel cycle in a breeder reactor. Increased research into Generation IV reactor designs began to renew interest in the technology, with multiple nations having projects, and as of September 2021, China is on the verge of starting its TMSR-LF1 thorium MSR.
Dozer is a stoner rock band from Sweden.
Thermal energy storage (TES) is achieved with widely different technologies. Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, building, multiuser-building, district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing summer heat for winter heating, or winter cold for summer air conditioning. Storage media include water or ice-slush tanks, masses of native earth or bedrock accessed with heat exchangers by means of boreholes, deep aquifers contained between impermeable strata; shallow, lined pits filled with gravel and water and insulated at the top, as well as eutectic solutions and phase-change materials.
The Molten Man is a fictional character appearing in American comic books published by Marvel Comics. Once a chemical engineer who longed to get rich, Mark Raxton was caught in an accident that saw his body get covered by an experimental organic-liquid metal alloy, which granted him superpowers, including the ability to generate extreme heat and radiation. Turning to a life of crime, he started off as an enemy of the superhero Spider-Man, but eventually was redeemed. He is also the stepbrother of Liz Allan.
Molten Lager is a live album by English rock band the Damned, released in October 1999. It was recorded in Mulhouse, France on 23 June 1994.
Cristallo is a glass which is totally clear, without the slight yellow or greenish color originating from iron oxide impurities. This effect is achieved through small additions of manganese oxide. Often Cristallo has a low lime content which makes it prone to glass corrosion.
Intrusive may refer to:
The Molten-Salt Reactor Experiment (MSRE) was an experimental molten salt reactor research reactor at the Oak Ridge National Laboratory (ORNL). This technology was researched through the 1960s, the reactor was constructed by 1964, it went critical in 1965, and was operated until 1969. The costs of a cleanup project were estimated at about $130 million.
Hrad Vallis is an ancient outflow channel in the Cebrenia quadrangle of Mars, located at 38.7° north latitude and 224.7° west longitude. It is 825 km in length and was named for the word for "Mars" in Armenian.
Karl Daniel Lidén is a Swedish drummer and music producer. He was the drummer for rock bands Dozer, Demon Cleaner and Greenleaf. He currently has a solo project called Vaka.
The Carolina Reaper is a cultivar of the Capsicum chinense plant. Developed by American breeder Ed Currie, the pepper is red and gnarled, with a bumpy texture and small pointed tail. In 2017, Guinness World Records declared it the hottest chili pepper in the world.
